Comment(by wjp):
From what I can tell, the issue is related to linbox and givaro both using
the
randstate stuff in givaro's gmp++_int.inl. On my home machine the internal
random states (a local static in {{{Integer::randstate()}}} ) in both end
up as different objects, but on lena they seem to
use the exact same object in memory, causing it to be deleted twice on
exit.
If anybody else wants to take a look, I tracked this down by putting a
breakpoint on mpir's 'randclear_lc' and looking at the rdi register which
is the pointer to the randstate.
