[Bug 1098750] Re: zsh5 crashed with SIGSEGV in hrealloc()
*** This bug is a duplicate of bug 1070820 *** https://bugs.launchpad.net/bugs/1070820 Yes, sorry, 5.0.5-1 from Debian Unstable on AMD64. I was able to reproduce it both with both the system zsh and a self-compiled debian package (but compiled with -O0 to ease debugging). I've seen this happen with the Zsh of Ubuntu 12.10 as well. Personally I'm considering just replacing hrealloc with relloc and pay the small (?) performance penalty (didn't look what other changes that would require). Of course, the bug might not be inside hrealloc per se, even if the crash happens there.. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1098750 Title: zsh5 crashed with SIGSEGV in hrealloc() To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/zsh/+bug/1098750/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1098750] Re: zsh5 crashed with SIGSEGV in hrealloc()
I've been able to crash hrealloc with ease and sadly too often writing
multi-line git commit messages. But if I do it as root (as it doesn't
have custom configs for zsh), I am not able to. It probably relates to
my zsh configuration as I was able to reproduce the problem with only
this loaded: http://github.com/zsh-users/zsh-syntax-highlighting
(version 4519467). Following backtraces are done with optimization level
-O0. Obviously h ending up being 0 is a problem..
