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, -- John McCluskey Postal Mail : John McCluskey, 808 de Bienville, Montreal P.Q.
