Comment(by fbissey):
OK back to singular problems. On my OS X (10.5.8 32bits) box I got another
test crash:
{{{
sage -t -long -force_lib devel/sage-
main/sage/rings/polynomial/toy_buchberger.py
}}}
and the following backtrace
{{{

This is with 4.7.1.alpha4. I'll try again on the linux x86 box this
weekend (and not lose the logs this time). It may be the last test I run
on that box for a while.
