[0.11.0] Internal compiler error with deduplicateInjectedParams=true for same-type @Inject params with different qualifier values

[burningfireplace]

Description

After upgrading Metro from 0.10.4 to 0.11.0, compileKotlin fails with an internal compiler error.

The crash occurs when an @Inject constructor has two parameters of the same Kotlin type and both parameters use the same qualifier annotation type with different qualifier values.

Expected behavior: compilation should succeed (or fail with a regular diagnostic), but it should not crash with an internal compiler error.

Context

• Kotlin: 2.3.10
• Reproducer target: JVM-only
• Extra observation: this did not reproduce in my testing when the duplicated injected type was String with equivalent qualifier setup; the repro consistently fails with a custom type (Action).
• Workaround: setting deduplicateInjectedParams.set(false) makes the same repro compile.

Paste the whole stack trace. Pasting just the first line is never enough context

Done. I edited the issue. Sorry, I wanted to keep the issue as lean as possible but naturally the full stacktrace is of more use...

[ZacSweers]

Thanks, does anything change if you don't use the @param: site target?

[burningfireplace]

Removing the @param: site targets does not change anything. It still crashes with the exact same internal compiler error. Let me know if there's anything else you'd like me to try to help debug this!

It shouldn't matter but I tried it on macOS + Linux on aarch64 and JDK25.

[burningfireplace]

I tried it just in case with OpenJDK21 and on Linux amd64 and get the same result everywhere.

Thanks for the repro, this looks related to a recent fix in #1882 but that might have fixed one thing at the cost of enums. Let me see about fixing both
