>Description:
If mod_php4 loads recode.so(GNU recode library) as its extension, apache2 cannot graceful restart, neither using apachectl
or kill -HUP. If this extension is removed, things go perfectly.

Below is the backtrace: (I dont know why recode.so will try to access mysql library, maybe that's the problem)

Both apache, php4 and recode is the newest version from cvs.
