Now I found out that pari caused some of these (I dont know exactly how many, but I will do a full test run later), because it was compiled without "- fno-strict-aliasing". I have written a bug report for that: - https://bugs.gentoo.org/show_bug.cgi?id=316139 In short: Add -fno-strict-aliasing to your CFLAGS and recompile pari and there should be less failing tests.
