Yeah, that's what I thought - please try to add configure options one
by one and see which one causes the problem.
Hint: I suspect it could be --with-curl or --with-openssl.

Unable to reproduce the issue with
'./configure' '--prefix=/opt/php' '--mandir=/usr/share/man'
'--with-apxs=/opt/apache/bin/apxs' '--enable-debug'
So a special configure option do this ... ?!?

Uhm.. Now THAT doesn't make any sense to me.
What Apache version is that? And which MPM are you using if it's Apache
2?
Also, please try to remove all those configure options which are not
required to execute this piece of code.
I guess just "./configure --with-apxs= ... --enable-debug" should be
enough.

Thanks for the link how-to debug PHP because with first
method I wasn't able to have a core file.

strace does not add any value.
But GDB backtrace could do that.
See this link http://bugs.php.net/bugs-generating-backtrace.php
