Apache SIGTERM with mod_php and libstdc++

[Gomez Henri <ne...@slib.fr>]

Hi toi all ,

I've got Apache (1.3.17 + mod_ssl 2.8.0) SIGTERM when using a php 4.04pl1
and mod_php 4.04pl1 with sablotron and pspell.

There are both present as extension loaded via php.ini.

If I remove sablotron (or pspell), apache with mod_php4 start and works
correctly.
The problem DIDN'T appears when using php in standalone ....

It seems that Apache got a problem when loading more than one external
modules using libstdc++.
I've got a similar error when trying to run apache with the mod_xslt from
Xalan-C Project....

Thanks for any help or informations

I think you are hitting the known glibc-2.1.x bug which rears its ugly
head when you have an executable which is not linked against libpthreads
which does a dlopen() on a shared library which is linked against
libpthreads.  If you simply link your httpd against libpthreads it should
sort itself out.  ie. LIBS=-lpthreads
