363 | # There is a devious bug in the MIPSpro 7.4 compiler: |
364 | # memcmp() is an inlined intrinsic, and "sometimes" it gets compiled wrong. | |
365 | # | |
366 | # In Perl the most obvious hit is regcomp.c:S_regpposixcc(), | |
367 | # causing bus errors when compiling the POSIX character classes like | |
368 | # /[[:digit:]], which means that miniperl cannot build perl. | |
369 | # (That is almost only the one victim: one single test in re/pat fails, also.) | |
370 | # | |

372 | # libc versions be used instead. This may cause a performance hit | |
373 | # but a little slower is better than zero speed. | |
