#12630: Assertion failed with BuildFlavour = devel2 -------------------------------------+------------------------------------- Reporter: pacak | Owner: Type: bug | Status: merge Priority: normal | Milestone: 8.0.2 Component: Compiler | Version: 8.0.1 Resolution: | Keywords: Operating System: Linux | Architecture: x86_64 Type of failure: Compile-time | (amd64) crash | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by simonpj): OK this is `substTy` called from `SimplEnv` i.e. in the simplifier. Again it's unlikely to be causing a problem but I'd like to nail what's going on. Do you have time to make a reproducible case? It doesn't have to be terribly small, but having few dependencies is helpful. You 8-file blob might do.
