Dear GHC Devs, I'm debugging an issue in our haskell-opencv library where a C++ exception that is thrown by the OpenCV C++ library isn't caught by the C++ try...catch block we have inlined in our Haskell code using inline-c-cpp. This results in the process terminating by SIGABRT.
Note that this only happens on OS X. In Linux the exception is caught correctly. I wrote a minimal isolated test case (which doesn't use OpenCV) at: https://github.com/basvandijk/darwin-cxx-exception-bug I wrote some instructions in the README on how to reproduce this and included some debugging notes. I'm not sure the bug is caused by a mis-configuration in my code or if it's a bug in nixpkgs, Cabal or GHC. Any idea what could be causing this? Bas
