Hi,


fno-strict-aliasing". I have written a bug report for that:

should be less failing tests.

Cheers,

as some of us know there a lot of failures on amd64 when running Sage's set of tests. 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 "- In short: Add -fno-strict-aliasing to your CFLAGS and recompile pari and there
