Have just moved some functions into modules and have fought all warnings when suddenly:

hellow554 commented 5 years ago

Do you have a small piece of code that you can show us that leads to the panic?

Antiarchitect commented 5 years ago

@hellow554 I'm trying to pick out one, but no success yet.

memoryruins commented 5 years ago

If you have a branch of the code that produces the ICE, we can try to help minimize it with you.

Antiarchitect commented 5 years ago

The problem is - I cannot reproduce it anymore. At least on another machine.

memoryruins commented 5 years ago

Based on the panic, it was an issue that occurred during incremental compilation. To reproduce, you would most likely need to build the project, make a similar change that led up to the ICE, then try to compile again.

Antiarchitect commented 5 years ago

Sorry guys, cannot reproduce :(

hellow554 commented 5 years ago

Maybe it has been fixed in the mean time (unlikely ^^). I guess you can close this. When it comes up again and you know how to do it, just reopen it. Thanks anyway for the report! <3
