internal error: ARR_WORDS object entered!
I'm using Windows 8.1 64-bit, the latest Windows SDK, and the latest Haskell Platform to rebuild a project. This project was previously building on Windows 7 64-bit with the same HP and a previous version of the Windows SDK. Source code for the project was unchanged, but my .cabal file was updated with different "extra-lib-dirs", "include-dirs", and "extra-libraries" fields.
When running this program after a cabal build I see the following error:
Segmentation fault/access violation in generated code
Using print statements I was able to locate the error as occurring during a call to an external DLL function.
I would assume this is a bug in my own code. Access violations are expected when misusing FFI, after all. However, I get a different error when compiling with profiling, and then executing with Main.exe +RTS -xc:
Main.exe: internal error: ARR_WORDS object entered!
(GHC version 7.6.3 for i386_unknown_mingw32)
Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug
This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.
Coming up with a minimal example would take time, but I can do that if someone thinks there is a possibility of this being a GHC bug. Is it possible for this message to appear under normal circumstances by programmer error?
