Package: libvte-2.91-0 Version: 0.46.1-1 Severity: grave There seems to be a bug in sid's libvte, such that dumping a large amount of text to stdout in a short period of time causes the terminal program to crash. "cat" of a file with 1MB of the letter "a" is sufficient to reproduce it.
I'm assigning this to libvte because I was able to crash xfce4-terminal, lilyterm, and termit this way, so it's clearly not specific to any one terminal program. I'm marking it "grave" because losing a terminal is pretty harsh.. any programs you've spawned from there (emacs, web browsers) abruptly exit too. I'm running this on an ARM64 chromebook (an Acer R13), which might be an unusual platform, just in case that makes a difference. I was able to get a stack trace by building vte2.91-0.46.1 and xfce4-terminal-0.8.4 locally with debug symbols turned on. It looks like this: Thread 1 "xfce4-terminal" received signal SIGABRT, Aborted. __GI_raise (sig=sig@entry=6) at ../sysdeps/unix/sysv/linux/raise.c:51 51 ../sysdeps/unix/sysv/linux/raise.c: No such file or directory. #0 0x0000007cb52229fc in __GI_raise (sig=sig@entry=6) at ../sysdeps/unix/sysv/linux/raise.c:51 #1 0x0000007cb5223df4 in __GI_abort () at abort.c:89 #2 0x0000007cb53dc59c in g_assertion_message (domain=domain@entry=0x7cb5fa3bb8 "Vte", file=file@entry=0x7cb5fac250 "/home/warner/stuff/debian/vte2.91-0.46.1/./src/vtestream-file.h", line=line@entry=790, func=func@entry=0x7cb5fac098 <_vte_boa_uncompress::__PRETTY_FUNCTION__> "unsigned int _vte_boa_uncompress(char*, unsigned int, const char*, unsigned int)", message=message@entry=0x5ccf97f720 "assertion failed (z_ret == Z_OK): (4294967293 == 0)") at ././glib/gtestutils.c:2432 #3 0x0000007cb53dc96c in g_assertion_message_cmpnum (domain=domain@entry=0x7cb5fa3bb8 "Vte", file=file@entry=0x7cb5fac250 "/home/warner/stuff/debian/vte2.91-0.46.1/./src/vtestream-file.h", line=line@entry=790, func=func@entry=0x7cb5fac098 <_vte_boa_uncompress::__PRETTY_FUNCTION__> "unsigned int _vte_boa_uncompress(char*, unsigned int, const char*, unsigned int)", expr=expr@entry=0x7cb5fac3f8 "z_ret == Z_OK", arg1=<optimized out>, cmp=cmp@entry=0x7cb5fa7420 "==", arg2=arg2@entry=0, numtype=numtype@entry=105 'i') at ././glib/gtestutils.c:2488 #4 0x0000007cb5fa0a94 in _vte_boa_uncompress (dstlen=65512, srclen=6140, src=0x7fc82a4618 "", dst=<optimized out>) at ././src/vtestream-file.h:790 #5 0x0000007cb5fa0a94 in _vte_boa_read_with_overwrite_counter(VteBoa*, gsize, char*, _vte_overwrite_counter_t*) (boa=0x5ccf75e420 [VteBoa], offset=offset@entry=0, data=<optimized out>, overwrite_counter=overwrite_counter@entry=0x7fc82b4714) at ././src/vtestream-file.h:911 #6 0x0000007cb5fa0e54 in _vte_boa_read (data=<optimized out>, offset=0, boa=<optimized out>) at ././src/vtestream-file.h:922 #7 0x0000007cb5fa0e54 in _vte_file_stream_read(VteStream*, gsize, char*, gsize) (astream=0x5ccf76dc50 [VteFileStream], offset=42288, data=0x7fc82b4750 "", len=24) at ././src/vtestream-file.h:1137 #8 0x0000007cb5f79dac in _vte_ring_read_row_record (ring=0x5ccf76e568, position=<optimized out>, record=0x7fc82b4770) at ././src/ring.cc:124 #9 0x0000007cb5f79dac in _vte_ring_discard_one_row (ring=0x5ccf76e568) at ././src/ring.cc:417 #10 0x0000007cb5f79dac in _vte_ring_maybe_discard_one_row (ring=0x5ccf76e568) at ././src/ring.cc:439 #11 0x0000007cb5f79dac in _vte_ring_insert(VteRing*, gulong) (ring=ring@entry=0x5ccf76e568, position=position@entry=2761) at ././src/ring.cc:551 #12 0x0000007cb5f7c604 in VteTerminalPrivate::ring_insert(long, bool) (this=this@entry=0x5ccf76e490, position=2761, fill=fill@entry=false) at ././src/vte.cc:247 #13 0x0000007cb5f7e694 in VteTerminalPrivate::ring_append(bool) (fill=false, this=0x5ccf76e490) at ././src/vte.cc:257 #14 0x0000007cb5f7e694 in VteTerminalPrivate::insert_rows(unsigned int) (cnt=1, this=<optimized out>) at ././src/vte.cc:2188 #15 0x0000007cb5f7e694 in VteTerminalPrivate::update_insert_delta() (this=0x5ccf76e490) at ././src/vte.cc:2234 #16 0x0000007cb5f7f9e0 in VteTerminalPrivate::insert_char(unsigned int, bool, bool) (this=this@entry=0x5ccf76e490, c=97, insert=insert@entry=false, invalidate_now=invalidate_now@entry=false) at ././src/vte.cc:2964 #17 0x0000007cb5f8b248 in VteTerminalPrivate::process_incoming() (this=this@entry=0x5ccf76e490) at ././src/vte.cc:3686 #18 0x0000007cb5f8bf08 in VteTerminalPrivate::time_process_incoming() (this=this@entry=0x5ccf76e490) at ././src/vte.cc:10428 #19 0x0000007cb5f8bfe8 in VteTerminalPrivate::process(bool) (this=this@entry=0x5ccf76e490, emit_adj_changed=emit_adj_changed@entry=true) at ././src/vte.cc:10452 #20 0x0000007cb5f8c244 in update_timeout(gpointer) (data=<error reading variable: value has been optimized out>) at ././src/vte.cc:10679 #21 0x0000007cb53b5484 in g_timeout_dispatch (source=0x5ccf575f80, callback=<optimized out>, user_data=<optimized out>) at ././glib/gmain.c:4674 #22 0x0000007cb53b4898 in g_main_dispatch (context=0x5ccf446770) at ././glib/gmain.c:3203 #23 0x0000007cb53b4898 in g_main_context_dispatch (context=context@entry=0x5ccf446770) at ././glib/gmain.c:3856 #24 0x0000007cb53b4c40 in g_main_context_iterate (context=0x5ccf446770, block=block@entry=1, dispatch=dispatch@entry=1, self=<optimized out>) at ././glib/gmain.c:3929 #25 0x0000007cb53b4ff0 in g_main_loop_run (loop=0x5ccf441450) at ././glib/gmain.c:4125 #26 0x0000007cb5b30934 in gtk_main () at /usr/lib/aarch64-linux-gnu/libgtk-3.so.0 #27 0x0000005ccef2d5b0 in main (argc=<optimized out>, argv=<optimized out>) at main.c:330 I can probably get you a coredump, if that helps. thanks!
