OK, we have isolated the problem now. Confirming its in the libgfortran. The
reason we did not see it on Linux is because we just did not run out of memory
yet and when the test program completes, it does actually free what was
allocated. We are failing to reuse an already allocated block so we were
allocating a new one for every single WRITE to the string.
Thanks for all your help.
