Hi,

I'd like to report a failure in one of the tests for
gmp 4.2, on a Pentium 4 running Linux 2.6.16. The
segment of output of interest is as follows:

make[4]: Entering directory
`/root/toolchain/gmp-4.2/tests/mpz'
PASS: t-addsub
PASS: t-cmp
ERROR: incorrect plain product in test 53

${dir}$tst
FAIL: t-mul
PASS: t-mul_i

(The test was in tests/mpz, if there is any ambiguity
as to what batch of tests was being performed.)

I am using GCC set to compile to the pentium4
architecture specifically. GMP was configured with
C++, FFT and MPBSD options enabled.
