I think the reason is buggy optimizations in pgcc-1.1.3 when long longs
are involved. -O2 activates more optimizations than -O.
My chess program is also using long longs and is miscompiled by
pgcc-1.1.3 as well. With pgcc-1.1.1 I do not experience problems.
Some weeks ago I posted a tiny code fragment to this list that exhibited
this problem. Is that the correct way to file bug reports? Is there any
patch available for pgcc-1.1.3 to correct this bug? Or should I wait for
pgcc-2.95? (If I'm not mistaken, egcs-2.95 should be released today.)
Is the long long problem just so fundamental (for example caused
by a deep bug in egcs-1.1.2) that a minor pgcc update should not be
expected?

Try again, it works for me.
