GHC panic: No skolem info
I got this GHC output:
/home/sven/DEV_LBM/lbm-talk-flow/mediabus-fdk-aac/src/Data/MediaBus/Audio/FdkAac/Encoder.hs:124:8: error:ghc: panic! (the 'impossible' happened)
(GHC version 8.0.2 for x86_64-unknown-linux):
No skolem info: k_ataY[sk]
Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug
It happens when I omit a type signature.
We do not have the resources right now to create a minimal test case, but I didn't want to ignore the request to file a bug report.
This happens in a small project available on github, I commited the specific code and tagged the commit 'ghc-panic' and added a comment in the code.
I doubt that is makes sense to paste the code here, so if anyone looks into this, please grab the code from github at: https://github.com/lindenbaum/mediabus-fdk-aac/blob/ghc-panic/src/Data/MediaBus/Audio/FdkAac/Encoder.hs
Sorry if this bug report is not helpful.
