(sorry, this should have been clarified earlier)
-O1 -g is fine
-O2 is fine
-O2 -g HANGS
dropping __attribute__((warning...) also makes the hang go away --- so
interaction with that an debugging?
gcc 4.1 is fine
gcc 4.2 is

Someone was able to reproduce the hang and pointed out the first attachment I
put up as edited without the __attribute__
Using built-in specs.
Target: x86_64-redhat-linux
Configured with: ../configure --prefix=/usr --mandir

(From update of attachment 16091)
doesn't show the hang as __attribute__ is missing
