I've see both cases segfault on debian j64, latest source update, (maybe
second-latest, the latest is "Remove character codes :. :: t. T. T: x.
y.") compiled with clang or gcc. Here's what gdb says for the second case:

The crash was intermittent for me, but I think it was caused by
uninitialized memory. I reassigned the internal character codes and the
uninitialized memory suddenly became meaningful. I have fixed that
problem for the next beta. I hope that is what you were seeing.

This last line crashes J, why?
JVERSION
Engine: j902/j64/windows

Apart from that, after updating base library from version 9.2.3 to
9.2.4, it still gives (in package manager) Installed 9.2.3 and Latest
9.2.4
I do have administrator rights.
