Please attach a preprocessed source (just add a -E option to the failing
compile line and the preprocessed source should be in math.o).

Thanks,
Sebastian

trunk@176058 from  Fri Jul 8 19:15:18 2011 does not ICE.
I have not tried 4.6.

--- Comment #4 from Martin Sebor <msebor at gcc dot gnu.org> ---
I can't reproduce an ICE with the attached translation unit so based on that
and on comment #3 resolving as worksforsome.  Please reopen if it persists with
trunk (and provide full details of compiler options again).
