There is no call to 'foo' in the test case here.  I guess you meant 'bar', but
even so executable test cases are strongly preferred over manual inspection of
assembly code.

FWIW, using the test case in the gcc-patches submission I've reproduced the bug
with both gcc-4.6.3 and gcc-4.5.3 on armv5tel-linux-gnueabi.
