These are compiler options but sometimes they won't help either.

If you see both the files side by side or do a diff -u you'll find that
they have exactly the same output with different ordering of events.
They fail for me in Redhat linux 7.0, gcc 2.96
Post-processing these traces using the time-stamps to re-order
events will probably solve the problem, but I'm not sure why this happens
to these two particular tests in red test-suite.
