ICE in GCC 2.96 20000523 (i686-pc-cygwin)

[Peter Joachim <joachim at dialup dot nacamar dot de>]

The CVS snapshot of GCC 2.96 20000523 (i686-pc-cygwin) experiences
an ICE if invoked with the following commandline:

//k/scratch/snapa/gco/stage3/xgcc  -v --save-temps
-B//k/scratch/snapa/gco/stage3/ -march=pentiumpro -O1 -ffast-math -S
hsl.c
The file hsl.i is attached to this mail as hsl.i.bz2.

Both -ffast-math and -march=pentiumpro have to be specified to trigger
the ICE.

//k/scratch/snapcvs/gco/stage3/xgcc  -v --save-temps
-B//k/scratch/snapcvs/gco/stage3/ -march=pentiumpro -O1 -ffast-math -S
