Hi,
I believe I have found a repeatable way to crash J using ?1x via having
read some big data first. Covid makes J ill?

If you compiled this yourself you're probably going to have to debug it
yourself. Crashes in thorn1main are happening during typeout of the
result. Probably an extended-integer value has a bad pointer.

It also happens for smaller arrays, but less consistently:

I cannot reproduce the crash in either j901-f or j903-h; however, in
either
version I occasionally see strange results like the following:
