Fails with m32c-elf in 4.3.4 also.
Note: does NOT fail in 4.4/trunk

Comment 7 Joel Sherrill 2009-07-17 14:32:49 UTC 
Patch committed.  Ran coverage to verify that it didn't introduce a new uncovered range of code.

Sorry to have broken it. Trying to get to 100% test coverage and eliminate dead code.

Stupid human error.  Clicked on wrong bug.
Comment 9 Joel Sherrill 2011-02-08 19:33:37 UTC 
Fixed as of gcc 4.5.2.  Closing.
