I can try that.
It is a null pointer though I believe.
interesting..??
On OpenBSD/x86, June, mentor, Cube, shownew, RehearseCode, showthread all fail to come up.
showheap comes up but doesn't show anything.
I've tried some of these in the past and they worked better, though I didn't use them for anything.
Maybe just a slow machine?
And I'm too impatient? Yes, but I don't think that's the problem.
xterm comes right up.
As does the empty showheap window.
Could be a wierd X server too, granted (Xming).
I can try Cygwin/X and I was thinking of buying a commercial one (just for
this few minutes of testing per month..)
If I don't set DISPLAY ..most still hang, except showthread.
Specifically showthread fails, but the others still seem to hang.
$ unset DISPLAY
$ ./showthread
***
*** runtime error:
*** Exception "TrestleComm.Failure" not in RAISES list
*** file "../src/vbt/TrestleClass.m3", line 33
***
Abort trap (core dumped)
I'm not sure that's how it should fail, but failure is expected.
I think I've seen the failure mode vary too, but again, failure is expected there.
So like we aren't even getting to XOpenDisplay.
Hey, not much to debug.. perhaps..
Here is Cube hung.
Again this is OpenBSD, not the most mature platform from the Modula-3 point of view.
Though imho the platforms are all highly similar.
$ gdb ./Cube

I should debug this more but not now.
And we should be sure to try these on other platforms, see if the hangs occur.
