I am facing problem in a Porting project(HP-Unix->Windows XP(64 bit))
where there are lots of C++->Fortran and Fortran->C++ calls.
There are some thousands of files including FORTRAN and C++ code.
After performing few operation which involves lot of FORTRAN->C++ and C
++->FORTRAN calling, application gives stack overflow error or behaves
unexpectedly.
It could just be that the stack is too small.


I tried with increasing the stack size in compiler options, but
problem remains the same.

one more thing which i have noticed is, whenever i am making a call to
a FORTRAN function there is a increase in
application memory by 4Bytes.
You mean 4 bytes each call, that doesn't go away when it returns?
In other words, a memory leak?


Yes, This same thing I tried by creating a small application where i
am calling
a fortran subroutine from C++. In this sample I have not written any
code and subroutine
takes no argument. Here also i am seeing this leak.

Can you post the code in your small application?

If you have a memory leak and your subroutine has no arguments, then my theory about strlen() is indeed complete nonsense.
