gmp hangs on "t-cdiv_ui" test while calculating gcd on MacOSX Lion

Hi, running "make check" for GMP 5.0.2 on macosx lion makes the tests
hang at this point:
the t-cdiv_ui is the last successful test the next test takes an
indefinite amount of time spawning a "t-gcd" process that uses 100%
cpu and never ends. The problem seems to be in GCD calculation.
This problem reflects also in real world usage. Actually I tracked
down this problem down by first experiencing it while using and
programming for Polly (a polyhedral optimizer for LLVM) that uses
indirectly (through a library called ISL) the GMP library. Polly hangs
in certain occasions and I was able to track back the problem to GMP.
Is the problem already known? There is a fix for this?
