Which compiler are you using? If I understand correctly, this is a known
problem with the Portland Group C compiler. If you haven't already done so,
try using gcc to compile LEaP, and see if that helps.

(Other people on the list may have better/different suggestions here; this
is a really frustrating bug that has eluded solution for some time. It
happens only with some compiler/OS/machine combinations.

...good luck...dac
