I have an idea what could cause the LinBox problem since the gcc 4.3
fix caused some of LinBox's internal tests to fail with an odd free at
exit. But the code in Sage itself valgrinds clean, so I doubt that is
it. Can you try 3.0.final to see if the problem is still there?
One issue we fixed is that we link the PolyBoRi extension statically
since linking all three libs dynamically causes double frees. See
#2822 for details. I fixed that in Sage by deleting all the dynamic
PolyBoRi libs, but that barely qualifies as a fix, more as a cheap
workaround. The problem does also no occur in PolyBoRi proper since
they also just link all the code statically in once big extension. But
the problem needs to be fixed on our end properly anyway since once we
have more than one extension using PolyBoRi the "static link fix" will
not work any more.

I suspect the above could be the same as #2983 - but I have no lead
there. I did valgrind it and all other Singular code we ran, but
nothing popped up. So leads on that one are *really* appreciated ;)
