Ugh, still not having an effect for me.. My problem is narrowed down to mysql.so, doesn’t matter where it is, or what’s going on it causes a bloody seg fault every time and I haven’t a clue why
I run a strace on it and got this: sigprocmask(SIG_BLOCK, ~[ILL TRAP ABRT EMT FPE BUS SEGV SYS], []) = 0 , but I haven’t a clue what to do with that :(

I had similar problem with freebsd 7.1/amd64/apache 1.3.41/php 5.2.8/postgresql 8.3.x and extension=pgsql.so

this is mine /usr/local/etc/php/extensions.ini

extension=mysql.so
extension=session.so
extension=xml.so
extension=pgsql.so
extension=gd.so
extension=curl.so

after httpd restart, apache go signal 11 and dumped core

my solution:
in httpd.conf add/uncoment line:

ServerName yourhost.yourdomain.extension

i had similar problem with 7.0-STABLE, except apache was not exiting (it was just hanging), but the cli version of php would core dump. fixed by putting imap at the end of the extensions (i did not have to move any others).

Thanks a lot for your post, this was exactly what I was experiencing. ANY php script crashed with signal 6 at the end. First I thought it was the ‘simplexml’ extension causing this, because disabling it fixed the problem as well. But I needed this extension, and finally, moving ‘mysql’ to the end of the list worked. I don’t use the ‘imap’ or ‘socket’ extensions, though. (php-5.2.2 on FreeBSD-6.1-RELEASE)

[...] & PHP5 which may seem related to use of extensions within PHP (extensions.ini), please read “PHP Crashes Caused By Extensions” [...]

Very helpful. I had segmentation fault problems with phpMyAdmin not opening after I made changes to php.ini and added extensions. Based on your advice, I looked at extensions.ini and found many duplicate lines. I removed all the duplicates and put mysql at the bottom and it fixed the problem. Thanks.
