I can't find any pattern to explain when the problem occurs and when
it doesn't, but it seems to be due to a change in make, starting with
version 4.4. By default, make now uses a FIFO rather than a pipe in
its jobserver implementation. You can override this with the make flag
--jobserver-style=pipe
In all cases where I've tried this, parallel make works again.
It wouldn't surprise me if there's a bug in Cygwin's FIFO
implementation that's responsible for this, but I haven't yet tried to
track it down.
There is some glibc? compatibility issue also with this recommended
workaround.
Could you elaborate? I don't know what issue you're seeing.
