Comment(by kcrisman):
> So maybe the best solution in practice for Sage is to add a check in
prereq that users aren't using Apple's broken compiler.
? So that no one using "just Xcode" can build Sage? I'm a little unclear
on what would have to change for ordinary users.
>Also we should have one server machine running Lion with a good compiler
to build binaries.
Certainly.
jhpalmieri points out on #12315 (where these comments should probably live
anyway)
> was pointed out on sage-devel that with SAGE_DEBUG=True, self-tests
pass. So it may be a compiler error; compiling with -O0 seems to work. It
may be just a single file (the one containing the bezout function) causing
the problems.
So perhaps a workaround would be to check for the "bad" compiler in the
spkg-install somehow and then do no optimization if that's the case.
Power users who need Pari optimized would be expected to have the
technical know-how to use the right one, and as you say the binary builder
could have this as well.
