Build error with idris 1.3.2

[dwarfmaster]

When running idris --build idris-ct.ipkg (or idris --checkpkg idris-ct.pkg), the build fails on CoLimits/CoProduct.lidr with the following error :

This is on master, on NixOS.

$ idris --version
1.3.2

A quick search lead me to the following issue idris-lang/Idris-dev#4254 which seems to be related to the second error.

Thanks @dwarfmaster for reporting. I tried building locally and I have no issues. This might be an issue due to stale .ibc files.
Could you try running idris --clean idris-ct.ipkg before building?

Thanks for the quick answer ! Unfortunately, it made no difference, I got the same error again.
