    The evidence against gcc 2.7.2 under Linux continues to mount.  I would
appreciate it if some of you can try this test on your Linux machines.

    I compiled the paranoia test program (netlib.att.com, netlib/paranoia)
both with and without optimization using gcc 2.7.2 on Linux 1.2.13.
With optimization off paranoia detected a flaw in the arithmetic
rounding mode (perhaps controlled by a compiler switch).  This is not
considered a serious flaw, and paranoia pronounced the arithmetic to
be OK.  However, when I compiled with -O2 paranoia found some serious
flaws and hung before completing the test.

    I compiled paranoia on the same machine using Visual C++ under
Windows 95 both with and without optimization and in both cases
paranoia found no problems and pronounced the arithmetic to be perfect.

    This doesn't prove that my hardware works correctly in all cases, but
it does show that gcc's optimization is seriously flawed.
