Package: less Version: 458-3 Followup-For: Bug #707824 Hi,
for me the bug only affects the i386 version of less, but not the amd64 version. The same test crashes on an i386 system, but not on an amd64 system (with the same package versions). test: dpkg -s dash | less -p '^(Package|Description(-en)?):' ========== i386 ========== crash: *** Error in `less': double free or corruption (fasttop): 0xb7ba6808 *** Aborted package versions: $ dpkg -l less debianutils libc6 libtinfo5 Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend |/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad) ||/ Name Version Architecture Description +++-==============-============-============-================================= ii debianutils 4.4+b1 i386 Miscellaneous utilities specific ii less 458-3 i386 pager program similar to more ii libc6:i386 2.19-18 i386 GNU C Library: Shared libraries ii libtinfo5:i386 5.9+20140913 i386 shared low-level terminfo library ========== amd64 ========== no crash $ dpkg -l less debianutils libc6 libtinfo5 Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend |/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad) ||/ Name Version Architecture Description +++-==============-============-============-================================= ii debianutils 4.4+b1 amd64 Miscellaneous utilities specific ii less 458-3 amd64 pager program similar to more ii libc6:amd64 2.19-18 amd64 GNU C Library: Shared libraries ii libtinfo5:amd6 5.9+20140913 amd64 shared low-level terminfo library Here's the backtrace for a crash on an i386 system, but it probably doesn't help much as it only contains the malloc error handling: *** Error in `/usr/bin/less': double free or corruption (fasttop): 0x565917d0 *** Program received signal SIGABRT, Aborted. 0xf7fdad70 in __kernel_vsyscall () (gdb) bt #0 0xf7fdad70 in __kernel_vsyscall () #1 0xf7e0a307 in __GI_raise (sig=sig@entry=6) at ../nptl/sysdeps/unix/sysv/linux/raise.c:56 #2 0xf7e0b9c3 in __GI_abort () at abort.c:89 #3 0xf7e486f8 in __libc_message (do_abort=do_abort@entry=1, fmt=fmt@entry=0xf7f3e65c "*** Error in `%s': %s: 0x%s ***\n") at ../sysdeps/posix/libc_fatal.c:175 #4 0xf7e4e76a in malloc_printerr (action=<optimized out>, str=0xf7f3e820 "double free or corruption (fasttop)", ptr=0x565917d0) at malloc.c:4996 #5 0xf7e4f3bd in _int_free (av=0xf7f82420 <main_arena>, p=<optimized out>, have_lock=0) at malloc.c:3840 #6 0x5656a4c0 in ??
