Those are rebuilt, tested more 3 times, but issue persists, the changes to

back-end @r196864 caused it.

The preprocessed sources alone isn't adequate to trigger this bug.

libvpx.a is required, do you need this archive ?

You're 100% correct.

It wasn't rebuilt properly because of ccache was enabled previously.

Closing bug as "works for me".

Thanks

 Bug #: 56145

   Summary: [4.8.0 ICE] Use of too much optimizations -O2

-ffast-math -floop-parallelize-all

Classification: Unclassified

   Product: gcc

   Version: 4.8.0

Status: UNCONFIRMED

  Severity: normal

  Priority: P3

 Component: tree-optimization

AssignedTo: unassig...@gcc.gnu.org

ReportedBy: vcho...@gmail.com

preprocessed source



When compiling the following source code from this url.

http://waix.dl.sourceforge.net/project/lame/lame/3.99/lame-3.99.5.tar.gz



gcc produced ice, when the particular combination of optimization flags are

used. -m32 -m64 made no difference. When adding -fwrapv to the command line it

stops gcc from produce the ice.
