#5268: ghci panic in ByteCodeGen.schemeE: unhandled case
---------------------------------+------------------------------------------
Reporter: patrikja | Owner:
Type: bug | Status: new
Priority: normal | Component: Compiler
Version: 7.1 | Keywords:
Testcase: | Blockedby:
Os: Unknown/Multiple | Blocking:
Architecture: Unknown/Multiple | Failure: None/Unknown
---------------------------------+------------------------------------------
To reproduce:
# install ghc from git HEAD 20110622
tar -zxf MonadicSystems-0.3.0.tar.gz
cd MonadicSystems-0.3.0/
cabal configure
cabal build
ghci MonadicSystems/Example/InputTransition3
Resulting panic is below.
Note that ghc reports a type error (no panic), while ghci panics.
I attach a snapshot of the code (which is not finished yet, but I thought
you may have use for the report).
