"Unable to increase stack" is one of the various messages that tells you that PolyML has run out of resources. It doesn't really tell you what the problem is though. It might be an actual problem or a temporary problem caused by a machine being overloaded.
This is likely connected to the recent change of platform. I will investigate this; maybe bumping the memory limit will resolve it.
