Bug#650318: Fwd: [Bug target/50906] e500 exception unwinding under "-Os" causes SIGSEGV
Hello,
The fix for GCC PR target/50906 has now been applied to gcc-4_6-branch,
so it should hopefully soon be automatically picked up in the Debian GCC
sources from that branch.
For reference, the commit log is attached below.
Cheers,
Kyle Moffett
