11 Christopher,
12
13 To clarify, the test failures I listed were for the two computers when
14 "-fno-strict-aliasing" _was_ added to the CFLAGS in building pari. Of course,
15 I did this in the ebuild with append-flags. The failures for the second
16 computer with "Killed/crashed" at the end of the failed test like,
17
18 sage -t -force_lib "devel/sage/sage/graphs/cliquer.pyx" #Killed/crashed
19
20 passed on the same computer when pari was built in which
21 "-fno-strict-aliasing" was _not_ added to the CFLAGS. I will check again and
22 report if otherwise. With "-fno-strict-aliasing" added I get 21 failures on
23 the laptop and 32 failures on the desktop; with 7 of the failures on the
24 desktop of the type "Killed/crashed".
