Building https://github.com/hth313/hthforth with ghc 7.6.2 on Linux or with 7.6.3 on ppc results in a ghc panic. (It works with ghc 7.2.2 on Mac OS X, I have not tested with any version between 7.2.2 and 7.6.2).

Use cabal to build hthforth, vector-bytestring 0.0.0.2 is needed when using ghc 7.6 and it can be downloaded from https://github.com/basvandijk /vector-bytestring (it is currently not on Hackage).

#8202: ghc panic applyTypeToArgs ---------------------------------------+----------------------------------- Reporter: hth313 | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.6.3 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time crash | Unknown/Multiple Test Case: | Difficulty: Unknown Blocking: | Blocked By: | Related Tickets: ---------------------------------------+----------------------------------- Comment (by hth313): I tried and failed to build HEAD (something with Cabal Main, I might have done something wrong, I am new to building ghc). I can make the problem disappear by eliminating the circularity introduced by Core.hs-boot, which indicates it might be #8184. On the other hand, the example in #8184 works with 7.6.3, while my code cause a panic.
