IntelliJ error "Assertion failed: Too many element types registered. Out of (short) range."

[jfehrle]

I just noticed this exception in IntelliJ. It's happened 81 times, last time on Jan 1. I'm working with the Coq source code, which is quite large.

Assertion failed: Too many element types registered. Out of (short) range.

Thank you for your report.
I've spotted a problem in the code, but I have difficulties reproducing the bug.

when does it happen ? does it happen after opening a lot of them ?
which version of idea ? are you using a recent (2017) one ?

[giraud]

I hope it is fixed in 0.34.
I will let this issue open a few days. If you don't see the assertion again during that period, I'll close the bug then.

I'm using the Community Edition 2017.2.5.

I don't know what is triggering it. IntelliJ doesn't make it easy to notice these: exceptions are logged but all the user sees is a tiny red icon is the lower right hand corner of the IJ screen. So alas, I'm almost guaranteed not to notice it right away. I'll let you know if I see more exceptions.

Thanks.

@jfehrle did it happen again ?

[jfehrle]

No, I've not seen this error since you made your changes. Jim
