When I sort it with -S 60M it work good. And it lookes like 'sort' ignores '-T /var/tmp' or TMP=/var/tmp or TMPDIR=/var/tmp ...
Can't reproduce this in the current version (2.0.11-6)
I can confirm that RESOLVED. I upgraded to current rawhide (textutils-2.0.11-6) and sort doesn't coredump. It also honoures TMP/TMPDIR settings and -T switch.
