The httpd configuration file

Hi,

the bug refers to Apache httpd 2.3.4, not 2.3.11.

When running httpd 2.3.4, I get in the error log the following backtrace:

*** glibc detected *** /usr/local/apache2.3/bin/httpd: free(): invalid pointer:

The build configuration is the following:
"./configure" \
"--prefix=/usr/local/apache2.3" \
"--with-included-apr" \
"--enable-mods-shared=all ssl cache proxy authn_alias file_cache charset_lite
dav_lock cache_disk" \
"--enable-load-all-modules" \
"--with-mpm=worker" \

The server settings are

I attached the configuration file (slightly edited for privacy reasons).

I tried to reproduce the problem in 2.4.1, but did not manage.

Best regards,
Silviu
