I am using D.J. Delorie's port of G++ to MS-DOS, and I am having a severe
problem with the G++ front end bombing randomly 30 to 80 percent of the time.
When it bombs, D.J. Delorie's dos extender (GO32), reports exception 2 at
various addresses.  Exception 2 is the NMI on the PC-AT (& clones),
typically generated by a parity error.  This error is quite puzzling, since
it is non-deterministic.  A compile may bomb, and then succeed on the next
attempt, or it may succeed after rebooting, or it may bomb 5 times in a row.
I suspect a subtle hardware interaction, possibly some condition that is
not correctly trapped, probably in the dos-extender code.  D.J. Delorie
has no email address in the documentation, merely a snail mail address.
Can someone advise?   

Thanks,
