Package: libapache2-mod-php5
Version: 5.4.4-11
Severity: normal
Dear Maintainer,
After running apache for a while, previewing or commiting a mediawiki edit
causes a child segfault:
[notice] child pid 23263 exit signal Segmentation fault (11), possible coredump
in /var/tmp/apache2-gdb-dump
When analyzing the coredump, the backtrace is 87k+ calls deep. The bt looks
like this:
