I think there is a access violation occurring in one of the dlls we are loading in __init__. However, these are precisely the same dlls we used in the old version of Nemo, so I'm quite puzzled how they are causing an access violation just because we are using a later version of Nemo.
I'll have to check all the julia code we use to load the dlls and see what we changed. I know that we are setting some memory functions now that we didn't use to set, so Julia can do counted_malloc. This is a real head scratcher, because I can't think of a plausible explanation for the problem. If I remove all the code to set the memory functions except the one to set the GMP memory functions, it complains that it can't find the GMP dll. That's despite the fact that we use this dll without problems in the old version of Nemo. Bill.
