Re: PHP 4.0 Bug #7670 Updated: PHP crashes when accessing IMAP mailbox

PHP's configure says checking whether to include debugging symbols... yes checking whether to enable Zend debugging... yes And file says that neither apache nor libphp4.so are stripped: [...]/bin/httpd: ELF 32-bit LSB executable, Intel 80386, version 1, dynamically linked (uses shared libs), not stripped [...]/libexec/libphp4.so: ELF 32-bit LSB shared object, Intel 80386, version 1, not stripped But the fact that I compiled Apache with StackGuard might cause this? I now recompiled Apache with normal gcc, but am unable to get a core file. Into which directory should Apache write its core?
