Hi all, I am seeing a very common crash now in zsh. The backtrace is here (and this it shows a corrupt stack / missing symbols). I'm still working on figuring out a reproducible version of the crash, but so far it seems to relate to sending SIGINT. gdb> bt #0 0x0000000000464f18 in wait_for_processes () #1 0x00000000004653c6 in zhandler () #2 0x000000000044567c in zfree () #3 0x000000000041e60b in execrestore () #4 0x00000000004647fd in queue_traps () #5 0x0000000000464b37 in dotrap () #6 0x0000000000465414 in zhandler () #7 0x0000000000439ae7 in waitforpid () #8 0x0000000000426fa4 in getoutput () #9 0x000000000046938a in quotesubst () #10 0x000000000046de99 in prefork () #11 0x000000000041f492 in execsubst () #12 0x000000000041f869 in execsubst () #13 0x0000000000425235 in execlist () #14 0x00000000004258fb in execode () #15 0x0000000000425a64 in runshfunc () #16 0x0000000000425e64 in doshfunc () #17 0x0000000000472dee in callhookfunc () #18 0x000000000047a543 in preprompt () #19 0x0000000000437600 in loop () #20 0x0000000000438606 in zsh_main () #21 0x000000000040e31e in _start () ---Type <return> to continue, or q <return gdb> frame Stack level 0, frame at 0x7fffffffccb0: rip = 0x464f18 in wait_for_processes; saved rip 0x4653c6 called by frame at 0x7fffffffccf0 Arglist at 0x7fffffffcbb8, args: Locals at 0x7fffffffcbb8, Previous frame's sp is 0x7fffffffccb0 Saved registers: rbx at 0x7fffffffcc78, rbp at 0x7fffffffcc80, r12 at 0x7fffffffcc88, r13 at 0x7fffffffcc90, r14 at 0x7fffffffcc98, r15 at 0x7fffffffcca0, rip at 0x7fffffffcca8 gdb> lib >From To Syms Read Shared Object Library 0x00000008008a8b90 0x00000008008ac8a8 Yes /usr/local/lib/libgdbm.so.4 0x0000000800ab0c70 0x0000000800ac86a8 Yes /usr/local/lib/libiconv.so.3 0x0000000800dbe590 0x0000000800deddc8 Yes /lib/libncursesw.so.8 0x00000008010087c0 0x000000080101e1b8 Yes /lib/libm.so.5 0x00000008012571d0 0x0000000801329358 Yes /lib/libc.so.7 0x000000080158f1d0 0x00000008015b2288 Yes /usr/local/lib/zsh/5.0.2/zsh/zle.so 0x00000008017c9cc0 0x00000008017e00f8 Yes /usr/local/lib/zsh/5.0.2/zsh/complete.so 0x00000008019e7a80 0x00000008019f0488 Yes /usr/local/lib/zsh/5.0.2/zsh/complist.so 0x0000000801bf4f70 0x0000000801bf8a38 Yes /usr/local/lib/zsh/5.0.2/zsh/parameter.so 0x0000000801dfce30 0x0000000801e00588 Yes /usr/local/lib/zsh/5.0.2/zsh/zutil.so 0x0000000802002e10 0x00000008020034a8 Yes /usr/local/lib/zsh/5.0.2/zsh/terminfo.so 0x000000080068ff70 0x000000080069fe68 Yes /libexec/ld-elf.so.1 -- Eitan Adler
