Hi! Did anyone com across this error when using context receivers with ksp enabled (posted in the thread):

context receivers are not yet supported by KSP due to the language feature still in experimental flag.

[Jiaxiang]

I am interested in the crashing though, while KSP does not support context receiver, we can still fix for crashing if possible. Can you provide a reproduce case for this stack trace?

[Charlie Tapping]

I use context receivers as part of my plugin but don’t have any issues with crashes. Do you mean you’re generating code that have context receivers present?

[Charlie Tapping]

Example here

[dave08]

No, I'm not generating any code with context receivers... as soon as I mark a function with context(...) fun... it gives me that error... I'm currently using #komapper and #kotlin-inject with KSP... and #komapper seems to support context receivers, since one of it's optional features uses them...

[Toshihiro Nakamura]

Komapper’s KSP processor can generate code that uses context receivers. I am running that code and have not encountered the above error.
