Package: libapache2-mod-php5
Version: 5.5.2+dfsg-1
Severity: important
After upgrading php and apache this afternoon, I receive many segfaults
from my local MediaWiki installation. Downgrading libapache2-mod-php5
and the various php5-* packages to 5.5.1+dfsg-2 fixes the problem.
Backtrace:
(gdb) c
Continuing.
Program received signal SIGSEGV, Segmentation fault.
