ld duplicate symbol when cache is enabled

[pedja1]

I am not sure if this is a bug or I am doing something wrong.
I get this error when trying to build for native/linux target
If I do as gradle suggests and disable cache, then it compiles, but it is painfully slow

> Task :linkDebugExecutableLinuxX64 FAILED
e: /home/user/.konan/dependencies/llvm-16.0.0-x86_64-linux-essentials-80/bin/ld.lld invocation reported errors
Please try to disable compiler caches and rerun the build. To disable compiler caches, add the following line to the gradle.properties file in the project's root directory:
    
    kotlin.native.cacheKind.linuxX64=none

I also encountered this error when I updated clikt from 4.4.0 to 5.0.3.

Calling rm -r /home/michal/.konan/kotlin-native-prebuilt-linux-* fixes the problem once, after calling compilation again the error is back.

Versions:

• Kotlin/Native 2.1.20 under Linux amd64.
• clikt 5.0.3.

this seems like a bug in the kotlin/native compiler. Maybe maybe a YouTrack bug report with them if there isn't one already?
