  I get a failure on make check on Core 2 with GMP 4.3.0:
  
  Seed GMP_CHECK_RANDOMIZE=1024574974 (include this in bug reports)
  /bin/sh: line 4:  1697 Floating point exception${dir}$tst
  FAIL: t-mul
  
  Note: I have defined GMP_CHECK_FFT=true in my environment.
  
  Can someone else reproduce this?
  
Yes.  GMP_CHECK_FFT should take a numeric argument.  For you, a variable
in the test code now becomes zero, leading to a division by zero.

Note that GMP_CHECK_FFT is meant to be undocumented, just like
GMP_CHECK_RANDOMIZE to avoid situations where users accidentally set
these parameters, and then they or we cannot reproduce any failures.

No GMP bug.
