I had been on the Insider fast ring for a few months to try out the latest bugfixes in the new Windows Subsystem for Linux. This is the first time I've hit any Cygwin trouble on an update, rolling back to build 14915 is making things better so far. Apologies for not collecting a cygcheck.out before rolling back, I've got a fair amount of work I need to get done right now so a working system is more important at the moment than helping debug this. But I'd be willing to get this insider build in a VM and test things out, I'm fine building cygwin from source and running things in gdb if there's a FAQ for what to look for somewhere. Advice, anyone?
