>How-To-Repeat:
(tested both as root and uid!=0 user)
download https://www.gnu.org/software/gcl//gcl-2.6.14.tar.gz
unpack the archive and cd into gcl-2.6.14
run: ./configure --prefix=/tmp/test

As observed, machine crashes at the same point in the configure run.

I have two mostly identical machines (one uses spinning rust,
the other SSD for storage), I'm willing to test patches.
