Dear all,
While working on [1] I stumbled on a strange segfault. Namely, with the
branch applied I got
{{{
sage: a = matrix(QQ, 1)
sage: a.randomize()
sage: quit
Exiting Sage (CPU time 0m1.48s, Wall time 0m5.80s).

<snip>
------------------------------------------------------------------------
Unhandled SIGSEGV: A segmentation fault occurred.

}}}
I indeed modified the randomization method to use flint random
generators, you can have a look at commits [2] and [3]. But I don't
understand at all where the error might come from.
Any help would be more than welcome!
