Thank you! Looks like https://youtrack.jetbrains.com/issue/KT-44801. Can you file an issue in Youtrack?

v
@Jilles van Gurp do you have the opportunity to check the presence of the exception with one of the last master’s build from the Kotlin TeamCity to see if this is the same as KT-44801?
j
I could test on a branch; do you have some quick pointers how I cn switch to that build?
@Victor Petukhov

You can download artifacts, for instance, from this build (
Download all
link in the top right corner), then add in your build scripts the link to the local maven repo with dowloaded compiler into 
repositories
sections: 
maven("file:///Users/<my_username>/Downloads/Kotlin_Public_Aggregate_builds_master_1.5.20-dev-985_artifacts/maven")
, after that just specify the Kotlin plugin version as 
1.5.20-dev-985
(corresponds to downloaded artifacts).
j
OK, thanks I might give this a try later.
I tried, it seems that the dependency management plugin we use don't play nice with offline repos. So, a bit tedious to fix and did not have time to do a custom build for this.
p
I have this problem as well and just attached a detailed Gradle build log to KT-45011
v
Thanks! I believe we’ll be able to fix that in 1.5.
BTW Could you minimize and anonymize if necessary your code which will still trigger an exception to be thrown, to provide us. Unfortunately, without any code, it will be very difficult to find the problem.
p
I will see what I can do. Stay tuned.

Sorry to say that after an hour or so, I have made very little progress. The source code for my project is open source on Gitlab and it appears from the Gradle log that the compiler is working on serialization code when it gets an internal error. The good news is that the project will build in about 10 seconds with useIR = false and fails even faster with useIR = true.
