Failure in the GMP test suite (ARM processor)

I'm getting an intermittent failure in one of the tests in the GMP 4.2.1
Hardware: ATMEL AT91RM9200 chip (an ARM-9 processor)
Operating system: Linux 18.104.22.168 kernel
Compiler suite: GCC 3.4.1 with GLIBC 2.3.2
This is an ARM cross-compiler running on an i686 machine
with Linux 2.6.4 kernel
==> configure --host=arm-linux --build=i686-linux --enable-cxx
==> make clean
==> cd tests/mpz
==> make check
Because the source is being cross-compiled, the various tests will not
so they must be loaded onto our hardware platform and run from there.
Problem: One of the tests, mpz/t-pow, is intermittently failing. I'm
attaching a sample output file from a run which attempts this test 20 times
and experiences 5 failures.
Other info: Of the 136 tests in the test suite (including the 14 under the
cxx subdirectory), this is the only one which has failed. Repeated runs of
this test seem to indicate a 20-25% failure rate. Because the failures are
intermittent, I'm more inclined to believe the problem concerns the GMP
library's interaction with the ARM chip rather than the GCC compiler suite.
