Bugzilla Bug 94377

libsdl doesn't build.

Reproducible: Always
Steps to Reproduce:
I've tried to emerge mplayer, and it required libsdl.
When making it didn't output any error, because it redirects the errors to
/dev/null, althought I've copy-paste the last command to check what the error was.
Actual Results:

and if you use just CFLAGS="-O2" ?

yes, it works :(
Or gcc has a bug or its happening something strange..

linux ~ # gcc --version

I can confirm that. Emerge stopped with the same error, -O2 worked.

What if you just remove -msse2?

Yep, without -msse2 it compiles just fine.

Filtered -msse2 in CVS... emerge sync in an hour and try again...
