I am using Intel Debugger 12.1 on Intel(64) Build [79.226.14] for a FORTRAN project. I compile the source files with debugging enabled (with -g) option. When I lauch idb as "idb a.out" and when I click View > Source Files; the left pane opened to list source files misses one file "vartypesFmod-mod.f90". I also have another module file "vartypesEmod-mod.f90" and it is listed. Is there a possibility that this could be a bug? I am experiencing the same behavior also in Intel Debugger Version 13.0 on Intel(64), Build [78.747.23].
