This seems to be a regression in gdb 8.1.1.  If you downgrade to gdb 8.0.1 on 
Cygwin the fault does not occur.  Obviously just a workaround.

I'm curious which version of gdb the OP was using within CLion.  In any case 
this issue should be pointed out upstream (to the gdb developers).  It doesn't 
seem to be a Cygwin issue after all.
