[FASTCGI] getgrgid() and getpwent() not thread-safe causes segfault in worker MPM

[Gea-Suan Lin]

Hello all,

We run apache 2.2 with worker mpm (threading model), and use mod_fastcgi
to run PHP 5.2.10 on FreeBSD 7.2-RELEASE-p2.

We found httpd will segfault sometimes (2~3 times in one hour) and tried
to gdb it, then I found bug is that getgrgid() and getpwent() are not
thread-safe.

I use getgrgid_r() and getpwent_r() to rewrite (as attachment) and in
this 12 hours it looks good.
