I mentioned the problems with PERL UNDER ULTRIX 3.1 (confirmed by at least one other message in this newsgroup) and TEX UNDER 4.0 (according to a report in this group). Your response about PERL UNDER ULTRIX 4.0 did not convince me yet that the compiler is not at fault. Moveover, you write that "Perl compiled here under Ultrix 4.0 fully optimized". Well, it "compiled" here too, WITHOUT ANY ERROR MESSAGES, nothing, it merely failed some of the validation tests. Without any optimizations, it compiled yet again without any error messages, but passed all the tests. I think I can safely infer that there is a SERIOUS problem with the optimizer or some other part of the mips compiler. Finally you mention that "There are some known limitations of the mips c compiler, including the way it deals with volatile & some non-ansi behavior." Either there are limitations, in which case the compiler should complain if these are exceeded, or else there are bugs (e.g.: different behaviors with different main memory sizes).
