Hello,

I have found the following problem on Windows XP with Cygwin 1.7.29:
If I build a Fortran dll and try to load it from Python by means of the cty=
pes module, python.exe crashes after LoadLibrary returned.
That problem may be reproduced with the files in the attachment.

Just type
tar -zxvf pyfor.tar.gz
make test

I have installed the following software:

Betriebssystemname	Microsoft Windows XP Professional
Version	5.1.2600 Service Pack 3 Build 2600
Python 2.7.3
ctypes 1.1.0
GNU Fortran (GCC) 4.8.2

Here is the output of the following commands:

$ uname -a
CYGWIN_NT-5.1 P5915 1.7.29(0.272/5/3) 2014-04-07 13:44 i686 Cygwin

$ ldd test.dll

        cyggcc_s-1.dll =3D> /usr/bin/cyggcc_s-1.dll (0x6fae0000)

$ make test
python test.py
loading ..
done
Makefile:4: recipe for target 'test' failed
make: *** [test] Aborted (Speicherauszug erstellt)

The problem seems to be related to the Fortran runtime libraries.
If the PRINT statement in test.f95 is removed, the problem disappears:

MODULE TEST
CONTAINS
SUBROUTINE RUN()
!~ PRINT *, 'RUNNING'
END SUBROUTINE
END MODULE

Best regards,
R. Resch
