Interesting. I guess the difference is attributable to our missing implementation of __CxxExceptionFilter on x86_64, so maybe the crash is due to code after that that should not run.
The most interesting thing that happens in the log before the exception is thrown seems to be a call to HttpCreateServerSession(), which is unimplemented in Wine. It may be worth trying to return success and see if that helps, though it may take extended debugging as other parts of httpapi are used.
Is there any chance of fixing this by releasing a wine-staging patch?
