Can anyone reproduce this on j902-b?
?. 100 $ 1x
Segmentaton fault
It also happens for smaller arrays, but less consistently:
?. 5 $ 1x
0 0 0 0 0 0 0 0
...
?. 5 $ 1x
Segmentation fault
I cannot reproduce the crash in either j901-f or j903-h; however, in either
version I occasionally see strange results like the following:
$ ijconsole-902-b
? 1x
...
? 1x
_5888
$ ijconsole-903-h
? 1x
...
? 1x
_255
? 1x
_256
