Re: Bug #3842: Apache segfaults IFF mysql support is compiled in

This is only an issue with the libmysqlclient.so library. If you grab the source tarball and compile your own mysql client libraries, the segfault disappears, or if you link against the static libs, the segfault disappears. I agree that there is a bug here, but I don't think it is in PHP specifically. -Rasmus On 16 Mar 2000 vorlon@netexpress.net wrote: > From: vorlon@netexpress.net > Operating system: RH Linux 6.1 / kernel 2.2.13 / glibc 2.1.2 > PHP version: 3.0.15 > PHP Bug Type: MySQL related > Bug description: Apache segfaults IFF mysql support is compiled in > > With newer versions of MySQL (>=3.22.32), Apache segfaults on startup.
