I run the testsuite with --enable-e500_double all the time and have not
seen this bug before.  It's possible that the bug you're seeing would be
fixed by this patch:

http://gcc.gnu.org/ml/gcc-patches/2008-02/msg01045.html

which was committed on the 6th of March.  The bug is very sensitive to
the environment in which the compiler is run, which would explain why
nobody else is seeing it.

Please update your checkout and rebuild the compiler.  If it still
fails, then please file a bugreport.  And if the bugreport could include
a backtrace (obtained with GDB), that'd be even better.

Thanks,
