I recently tried building and running some old fortran code using what I 
think is the current version of cygwin gfortran (--version reports 
9.3.0) and was surprised to get a run-time error message saying that a 
format statement was missing a left parenthesis. There was no format 
error in that line (the same code ran previously on cygwin, and runs now 
on debian stable). Furthermore I would not expect to see a syntax error 
message at run time. I got around the problem by switching from cygwin 
to a debian virtual machine, but then went back for another look at 
cygwin, using different (old, tested) code. Again I hit a segfault, this 
time with no explicit message, but stepping through gdb tracked the 
error to a write statement. Copying the offending write statement into a 
simple example failed to reproduce the error.
