I have confirmed this problem on Cygwin reported here:

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=35063

I am not very familiar with the windows environment.  Having patched most of the 
gfortran I/O library in the last 2-3 years I can say that we do a lot of memory 
allocation for I/O.

On Linux based systems we do not see any issues (checked with valgrind).  This 
problem acts like a failure to free memory.  I do not know what is meant by the 
term "handle" other than a pointer to an allocated block of memory.

Those of you most familiar with the Windows environment could perhaps help here. 
    Is this a bug in Cygwin memory management?

I will be happy to provide additional information as soon as I know what is 
pertinent.

I have latest Cygwin as of about two weeks ago and I can provide a gfortran 
binary if needed.

Regards,

Jerry
