Hello all,
I have been working for some time on a patch that does a realtime harmonic analysis of an incoming MIDI stream and constructs probability tables for creating second-order markov chains based on the input. The patch is fairly large and complex; the probability calculating abstraction (fairly small in itself) is called 13x13x13 times.
Recently, pd has occasionally died when I try to open this patch, but I could get it to open after a few failed attempts. Now, quite suddenly, it won't open at all; pd generates an invalid page fault whenever I try to load this patch. It opens all other patches without trouble. Most puzzling to me is that I haven't actually made any changes to the patch; I added some comments to the abstractions that are called by the parent patch, but made no functional changes immediately before this started to happen. I thought that perhaps the file was corrupt; I rebuilt the patch from it's constituent parts, it worked perfectly. I saved it under a different filename, closed it, tried to reopen it, and got the same error message. I even checked my resource meters, and nothing (memory, etc.) seems to dip when trying to open this patch. I'm stumped.
What could I have done wrong to cause behavior like this? I'm running pd .33 patch 1 with the iemlib extensions on win 98. The error message I get is:
PD caused an invalid page fault in module PD.DLL at 015f:10046e98.

Any help is greatly appreciated, Greg
