I can reproduce this issue on Ubuntu 10.04 (gcc 4.4.3).
That means:
$ gcc -o foo foo.c -fmudflapth -lpthread -lmudflapth
$ ./foo
- mf:

I bet the issue is that Ubuntu's GCC passes --as-needed by default (non
standard really).

Of course libmudflapth needs to come first, otherwise it doesn't override
libpthread symbols it means to override.
If it doesn't, that is a user error though.

Let's get it documented? One sentence should do. I think it's pertinent because
-lpthread will most of the time come before user supplied compiler flags.

I think libmudflapth does have a dependency on libpthread which is causing this
issue. I think libmudflapth have a weak check in it too.
w pthread_join

-lpthread
I think it is better to use -pthread instead.
