There could be several reasons for this I found out.
I had this problem, thinking it was having the "gpu-platform" : "1", switch, but for some reason on the first initial run, it crashes trying to create the bin, me by removing "gpu-platform" : "1",, firing cgminer up stopped the first initial crash, after the first initial run without "gpu-platform" : "1",, I would edit the config and reinsert "gpu-platform" : "1",, and it would run fine. Then I started to mess around with thread concurrency, having it to high, crashed my cgminer.
