I was avoiding using mudflap for a while due to the high volume
of violations that I could not explain. Recently, they all
disappeared which made me happy and I started using mf. I got
zero violations since.
When I had time to think about it I figured this just cannot
be true.
I have now confirmed that using -fmudflapth causes most of the
checks to not happen. -fmudflap seems to have all checks done.
In the past -fmudflapth did the job. Something changed.
The help suggests that the two options have a function but it
is not clear (to me) what it is. Attached is a sample that
demonstrates how a simple violation is missed when -fmudflapth
is used (the program does not use threads).

This could be an unintended side-effect of rth's libmudflap pthreads
changes a week or two ago.
