in what type of statement have you the segfault ?
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.
