Description Stephan Fietzek 2009-09-30 14:14:25 UTC

It's seems that the hardened gcc 3.4.6 is bugged when using -fno-strict-aliasing -O2. It overlaps the address of a stack variable with the return address.
This leads to crashing apps like clamav-0.95.2 scanning certain files.

Reproducible: Always

GCC 4.3.4 is stable on hardened.  GCC 3.4.x is frozen/not being worked on. 
Closing as WONTFIX.
