kargl at gcc dot gnu.org changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |kargl at gcc dot gnu.org --- Comment #1 from kargl at gcc dot gnu.org 2011-05-09 19:34:29 UTC --- Your code compiles on x86_64-*-freebsd with 4.6.1 20110509 and gcc version 4.7.0 20110509. There have only been a handful of patches to the 4.6 branch since 20110325, but it isn't clear if these should help. valgrind on the 4.6.1 f951 does not show anything bad. This could be target specific. Can you get a backtrace with a debuggers?
