[Bug 203744] Re: konqueror causes segfault in libpcre

Tue Mar 18 23:42:13 UTC 2008

I installed libpcre3-dbg under Hardy and ran konqueror 3.5.9 under gdb
and got a backtrace with this repeating over and over (the eptr and the
exact string change).  Looks like it's getting into some sort of
infinitely loop trying to parse the page.
