GHCi failed to load pthread on windows.

After doing clean install of Haskell platform on windows following error happens.

No other mingw instances on path. Tried reinstalling with default locations. Still no success.

Compiling hello world with ghc suceeded, seems that issue is with ghci only.

Thanks for your report. In which version of Windows are you seeing this?

Looking at the imports (via dumpbin) of the 64-bit ghci.exe from 8.4.3 on a Window 7 installation, it seems to only depend on kernel32.dll, user32.dll, and msvcrt.dll. Loading ghci.exe, then looking at the loaded dlls (via Process Explorer), I do not see pthread.dll. I looked in the typical locations for dlls on this machine and do not even see a pthread.dll.

I am working on windows 10. Tried installing on another win 10 machine and everything works flawlessly there. Perhaps it is interfering with some other software.
