ports/158374: databases/firebird21-client coredumps

[Michael Maguire]

Hi everyone,
I'm posting this to the bug and to freebsd-questions in case anyone can
help me out with advice on how to investigate further.
This is in regards to:
http://www.freebsd.org/cgi/query-pr.cgi?pr=ports/158374
I'm not sure if I jumped the gun on submitting the PR because the fix
only partially fixed it and the next problem may or may not be related.
=====

Actually I played with this further and maybe these things are pertinent:


Everything works fine on a FreeBSD 9 VM I have:
FreeBSD 9.0-CURRENT #3: Sun Apr  3 20:41:14 PDT 2011
gcc (GCC) 4.2.2 20070831 prerelease [FreeBSD]

I never had to patch anything and it is the exact same version of
Firebird (and PHP).


I did try patching the FreeBSD 8.2 machine (as described in the other
PR) and it only sortof worked....
It connects to a firebird database and everything seems fine (it outputs
data from the database) until the end of the script where it still
segfaults.
I should point out that php scripts that don't connect to firebird don't
segfault and I tried eliminating all other extentsions.

I'm not sure how to get a better backtrace (I tried compiling
php/php-extenstions/firebird with debug and they aren't stripped):

# gdb php php.core

Thanks,
Mike

PS
Firebird itself works fine if run from isql-fb.
