Reported By: xris at farcaster dot net
Status: Open
Bug Type: Gettext related
Operating System: GNU/Linux 2.4.20
PHP Version: 4.3.3
New Comment:
Okay, i just managed to get PHP to segfault using the
command line version.. here's the backtrace:
#0 0x409bdc4d in _int_free () from /lib/libc.so.6
#1 0x409bcaba in free () from /lib/libc.so.6
#2 0x081b0ad2 in shutdown_memory_manager ()
#3 0x08196956 in php_request_shutdown ()
#4 0x081cef1c in main ()
#5 0x4095f7a7 in __libc_start_main () from /lib/libc.so.6
I guess this doesn't look too good and/or doesn't help much.
Any hints on how to proceed?

Sorry, i can't - the bug seems to occurr in larger scripts
only... (at least i wasn't able to reproduce in a small script)
I'd love to provide a backtrace, but all my efforts so far
haven't been very successful, neither by following the
steps here at bugs.php.net nor the description at the
apache.org site.
It doesn't matter if i try gdb or strace, both tools quit
with s.th. like: "ptrace: Operation not permitted"
Any hints on that? I googled for nearly an hour but couldn't
find a reason for gdb to fail with that err.
I tried gdb/apache with "-X -PHP4" as well as attaching to
the apache process afterwards but i keep getting the
mentioned ptrace error - or do i have to use Apache1.3 to
trace the problem? Any help is greatly appreciated.

And/or provide a backtrace of the crash (without --enable-debug, of
course as you said it happens only then)

Could you try providing a short script that uses gettext functions
which can be used to reproduce this..?

It should be a relatively simple fix. I am about to get on a plane,
but I will have a look when I get a chance. I have a feeling that now
that we think we know there is a string somewhere in gettext not
getting null-terminated someone will jump in and find it before me.

Good guess. A 4.3.3 without Gettext doesn't show the symptoms.
How to proceed next? ... i wouldn't be too fond of the idea
having to reimplement _() in php ...
