Thanks for your reply.
I was trying to port SPEC CPU 2000 (benchmarks), and one of the tests
failed. I boiled it down to the attached program. For performance reasons it
could be perfectly valid not to use memset(), but I agree that the code
looks a bit odd.

Is 2.96 20000731 current? I thought 3.0.1 is.

Use "-fno-strict-aliasing"?

Why don't you use memset() to clear the struct in the first place?
