Evaluated a CAF (0x7c8a18) that was GC'd!
I'm getting this on executables built with -ticky
with a recent HEAD
bash$ ./gamteb 5000
gamteb: internal error: Evaluated a CAF (0x7c8a18) that was GC'd!
(GHC version 8.11.0.20200402 for x86_64_unknown_linux)
Please report this as a GHC bug: https://www.haskell.org/ghc/reportabug
Aborted (core dumped)
That's extremely alarming. This is in nofib/real/gamteb
.
I've also seen it happen on nofib/spectral/mate
.
Is anyone else seeing this? Can I do anything to provide more info?
