Hi,

I just installed 5.2.0, and got the same warning about mismatched
libraries and the same segfault.

The library versions are *newer* than what both 4.9.3 and 5.2.0 from the
distribution are built against.  This may or may not be the cause of the
problem; either way gfortran is currently broken on Cygwin 64.

If your sytem is running fine, don't upgrade :-)

Building gfortran myself under Cygwin has not been a happy experience
for me in the past (although I do it quite regularly on Linux, of
course).  Maybe I'll give it a spin.

Regards

	Thomas
