My humble opinion on the subject: The only sane principle will probably be "no bugfix/modification without a regression test" but I guess this isn't going to happen ... My limited experience is with Perl's testsuite shaking bugs in FreeBSD's libraries: bin/51535, bin/49087. And with FreeBSD's malloc completely trashing the performance of any realloc addicted program, like Perl. Regards, Adi
