[sage-devel] Re: MPIR and gcc-4.3.2

This thread got a lot of replies on mpir-devel which didn't show up here for various random reasons. The gist is that the problem only occurs with debian gcc 4.3.2, and only with fstrict-aliasing which is enabled by -O2. There's a discussion there about what best to do about it in Sage and MPIR.

[sage-devel] Interface for evaluation of polynomials distinguishes between 1 and >1 variables

Hello, I am not sure whether this can be called a bug, but I've noticed a weirdness while working with Sage (5.0). For any positive integer n, I can define a ring R(n) = PolynomialRing(QQ, polynames(n)), where polynames(n) is the list ['x1','x2',...,'xn']. This ring is just the polynomial ring in

[sage-devel] Re: MPIR and gcc-4.3.2

Both GMP and MPIR documentation complain about gcc-4.3.2, but I haven't seen an explicit code snippet that triggers faulty behaviour. Closest I found was this: http://trac.mpir.org/mpir_trac/ticket/291 which indicates that at least something in "rootrem.c" goes wrong. I'd assume the testsuites of

[sage-devel] MPIR and gcc-4.3.2

So what's the motivation for refusing to build MPIR with gcc-4.3.2? The configure script essentially just says "it's broken" without specifying how or why. I have built MPIR with gcc-4.3.2 on a GNU/Linux x86_64 system with -march=nocona and built gcc with that MPIR and I had no problems at all.
