OK, I'll leave it running and report tomorrow in the other thread.

Very unlikely, but you can test it anyway. This requires the specific case of a parameterless function that doesn't trigger the VTBL opcode ending up as the first opcode of a function, and the only case where it could cause that other bug is with calls to non-native functions, as native ones just spit out the error reported in this thread. (AFAIK the function called needs to be a parameterless static function to trigger this)

This should be fixed now. If it somehow still happens (it shouldn't), this bug report can be reopened.

Moving this to the On Hold Bugs forum so it doesn't get lost or accidentally closed.

It hasn't happened since. From what others have said it looks like it is a recurring thing, but a rare one. But I really can't remember more than what I posted. If it happens again, I'll be sure to make a proper record of the message.

I'm afraid we need the exact error message. Unexpected JIT error means that something threw an exception while it was compiling a script function to native code. The rest of the error is the most important part of the message. Filtering by "menu" or "native" lists way too many source lines.

Yeah I've had this randomly happen to me this year, probably less than 10 times. Absolutely zero clue what causes it or how to even reproduce it.

I think I've seen that happen a couple times, but it's almost impossible to reproduce intentionally.

I'm sorry that this may be too vague to be useful, however, I thought I'd record it JIC (just in case).

I was playing a game with a map loaded but, as far as I know, nothing in it has any ZScript (or even DECORATE) modifications.

I pressed Esc and the menu did come up, but there was also an error printed to the screen/console. I thought that I had a logfile running, so I didn't pay too much attntion to the exact working but, it turns out that I forgot to set up a log file.

The error was something like:

Unexpected JIT error cannot make native menu call.

It was something like that anyway. Certainly "unexpected JIT" was in there, as was "menu" and "native".

Like I said, sorry if it's too vague.
