Good day. I'm using GHC 6.2.1, and have had much success with it. However, yesterday I got a strange error I've never before seen.
Mosaic: internal error: stg_ap_p_ret Please report this as a bug to glasgow-haskell- [EMAIL PROTECTED], or http://www.sourceforge.net/projects/ghc/ I'm running Windows XP Service Pack 1. The only obvious thing from the run is that several generation 1 garbage collections resulted in a substantially smaller allocation than before (99% of all space was free over these two collections) and something "bad" happened. I've included the console data (trace output, the -Sstderr output, the parameters used to run the program, the OS version at the top...), as well as the code for the main module, the .hi file, and the .o file (in case these help). Neither the main module nor any of its included modules use FFI in any capacity. Use of unsafe IO is limited to caching and tracing. Note: the reference to "threads" solved, killed, etc. are to an abstraction of a "DeductiveThread" for a backtracking algorithm, which is the core logic of this program. No modules in this program use Control.Concurrent in any capacity. I'd be happy to provide additional details, additional source, etc. I'm going to rerun the program and see if the problem reoccurs: the program does use randomness, so it's possible that the problem won't appear again. The easiest way to contact me is at this email address. I check it regularly during the week, and periodically over the weekend. Please don't hesitate to ask if you have any questions, or if there's some other way I can help. I've quite enjoyed the GHC product, have written some significantly non-trivial programs using it, and would be happy to assist in making it a better and more robust tool. Thanks, and I look forward to hearing from you... oriel __________________________________ Do you Yahoo!?
