Ubuntu 11.10 64bit mex file compilation

Hi!

I recently started using MatlabR2011b on Ubuntu, largely for compiling my FORTRAN mex-files for use on linux systems (clusters).

However, I am encountering problems in executing them, after compiling them out of Matlab.

For example, when I compile the supplied example timestwo.F, I get a segmentation violation.

What could be the problem? Could it be, because I am using a newer version of the gcc-compiler? Though the compiling runs without errors.

Here is the error report:

>> timestwo(2.0)
