We're mostly C/C++ people here. You can also ask questions at fortran@xxxxxxxxxxx, and that may be a better place for Fortran specific issues.

I took a quick look at the compiler source code, and it appears that -frecord-marker is implemented by automatically inserting a function call into the main program. That means that it will only work for you if you compile the main function in Fortran, not C++. I have no idea whether this is a bug, a misfeature, or working as intended. Ian
