[tree-ssa] Make check bombs my system on noncompile/20010425-1.c

Hi,

Last night I bootstrapped tree-ssa and wanted to test it, but my system
completely deadlocked (as in: must reset my computer because it doesn't
respond to anything at all) somewhere when running gcc.dg/noncompile. I
had already let it run for well over half an hour to see if the thing
would just time out, but apparently it doesn't.

This morning I re-bootstrapped (this time with checking disabled) and
ran the test suite reniced and verbose. My computer still bombed but at
least I could now see that it bombed on noncompile/20010425-1.c, which
is consistent with what I saw in gcc.log last night. Here's the last few
lines of the log:

/home/steven/devel/tree-ssa/gcc/testsuite/gcc.dg/noncompile/20010425-1.c:8: error: for each function it appears in.)^M

After this, my computer hang.  This is completely repeatable for me.

 Anyone else seeing this, too???

Gr.
