>Description:
apache-2.0.49 and php4-4.3.5_7, but the problem exists with apache-2.0.48 and php4-4.3.4_6 as well (only these two combinations were tested).

apache coredumps on any command aside from starting, but only coredumps after everything has completed succcessfully.

boris# httpd -t
Syntax OK
Segmentation fault (core dumped)

boris# apachectl stop
Segmentation fault (core dumped)

(gdb) where
#0  0x28886b20 in ?? ()
#1  0x28340384 in exit () from /lib/libc.so.5
#2  0x0806bbd1 in destroy_and_exit_process () at main.c:215
#3  0x0806c7c5 in main (argc=2, argv=0xbfbfec44) at main.c:564
#4  0x0805d0b2 in _start ()

the 'stop' leaves a runaway process, which must be kill -9'd.
root     627 99.0  0.3  4596 3172  ??  RLs   4:30PM   1:07.05 /usr/local/sbin/httpd -k start

This makes log rotation impossible. More annoyingly, a lot of php functions fail internally with strange libc errors. Uploading files via  POST is one of the major things broken. This fails because fdopen() returns EINVAL after mkstemp returns a valid file descriptor inside the php code.
>How-To-Repeat:
install apache (ports/www/apache2) and php4 (ports/lang/php4) with no changes [aside from using postgres instead of mysql].
