GHCi crashes under Windows Millenium

[guest]

GHCi fails to launch for me under Windows Millenium. The command:

ghc -v --interactive

produces the following:

   ___         ___ _

at which point GHCi fails with the generic error message (roughly translated from French):

Ghc provoked an error in GHC.EXE. The program Ghc will now be stopped.
If you continue to encounter problems, try to restart your computer.

Restarting the computer, obviously, didn't help.

I am using GHC 6.6 under Windows Millenium, which was set up using the standalone Windows installer. I can use the compiler from the command line without any problems, but whenever I try to launch GHCi from the Start menu or using "ghc --interactive", I get the above error message. Please note that GHCi v6.4.2 works flawlessly on the same machine (a rather old Pentium III 650 MHz with a modest 128 Mo of RAM, if such things matter).

Hi,

I believe I've diagnosed the problem, but wondered if you could try out the fix before I take it further. If you download

 http://galois.com/~sof/ghc9x.zip

and unzip its contents on top of a ghc-6.6/bin directory, i.e., overwrite the ghc.exe that's in there [you may want to copy the original off to the side first, just in case..], GHCi may just work a little bit better for you.

Please let me know if that helps; thanks.

Hello,

I was the one who submitted the original bug report and I can confirm that your fix did indeed correct the problem on my machine. In fact, replacing ghc.exe did the trick with or without the accompanying dll, so it doesn't appear to be essential as far as I can tell. In any case, thank you very much for taking the time to investigate this, your efforts are certainly appreciated.

Great, thanks for the quick feedback; evidence that the right itch has indeed been scratched.

I suspect you may have that DLL kicking around somewhere else on your load path..

I'll leave the ticket open at least until the necessary changes have been committed.

Have the changes been committed yet? If not, where are they? Is there a problem with them?

Sigbjorn has confirmed that the changes have been committed, and it sounds like they work for everyone.
