https://sourceware.org/bugzilla/show_bug.cgi?id=16544 --- Comment #1 from Razvan Ghitulete --- When enabling the plugin gold/workqueue.cc:319 seems to run gold/plugin.cc:1407 as well.

[Bug binutils/16638] New: AR - Segmentation fault due to call stack overflow
https://sourceware.org/bugzilla/show_bug.cgi?id=16638 Bug ID: 16638 Summary: AR - Segmentation fault due to call stack overflow Product: binutils Version: 2.24 Status: NEW Severity: normal Priority: P2 Component: binutils Assignee: unassigned at sourceware dot org Reporter: razvan.ghitulete at gmail dot com AR seems to have some issues when run with a plugin and the -r flag. More specifically: ar rcsD arch.a elf_obj bitcode_obj -> Segmentation fault ar csD arch.a elf_obj bitcode_obj -> OK It seems that the issue occurs specifically when resolving the -r flag on a callchain invoked from replace_members() in ar.c. ... #2 bfd_check_format (abfd=0x732e40, format=bfd_object) at bfd/format.c:95 #3 bfd_plugin_get_symbols_in_object_only (abfd=0x6e75b0) at bfd/plugin.c:157 #4 add_symbols (handle=0x6e75b0, nsyms=2, syms=<>) at bfd/plugin.c:280 #5 claim_file_hook() from bfd-plugins/LLVMgold.so #6 bfd_plugin_object_p (abfd=0x6e75b0) at bfd/plugin.c:451 #7 bfd_check_format_matches (abfd=0x6e75b0, format=bfd_object, matching=0x0) at bfd/format.c:336 #8 bfd_check_format (abfd=0x6e75b0, format=bfd_object) at bfd/format.c:95 #9 _bfd_write_archive_contents (arch=0x715be0) at bfd/archive.c:2149 #0 bfd_close (abfd=0x715be0) at bfd/opncls.c:703 #1 write_archive (iarch=0x6e5210) at binutils/ar.c:1161 #2 replace_members (arch=0x6e5210,files_to_move=0x6e51e0,files_to_move=0x6e51d8, quick=0) As far as I can tell when invoked from replace_members the abfd->my_archive never gets filled in, and bfd_plugin_object_p passes it like this to claim_file_hook in the plugin, which obviously cannot fill it in since the plugin API exposes the abfd as a (void*). Nonetheless in bfd_plugin_get_symbols_in_object_only() due to the abfd->my_archive being NULL there is a new bfd object created 0x732e40 from scratch as opposed to the initial 0x6e75b0. This basically seems to be the loop that overflows the stack. -- You are receiving this mail because: You are on the CC list for the bug. ___ bug-binutils mailing list bug-binutils@gnu.org https://lists.gnu.org/mailman/listinfo/bug-binutils
