Re: [PHP-DEV] Bug #4045: Apache segfaults when PHP is loaded From: Rasmus Lerdorf (rasmus <email protected>)

MySQL from rpms? If so, try compiling from source and see if you have the
same problem.

It seems to me that I remember chasing down IO_new_*() related problems
before and it ended up being a glibc mismatch problem of some sort.
