Code coverage run problem, no *.dyn files occur

Code coverage run problem, no *.dyn files occur

I have a dll that I compiled with the following ifort options:

/Qcov-gen
/Qcov-dir:c:\temp\coverage

When compiling I get the files PGOPTI.SPI and PGOPTI.SPL into the directory. The .SPL file is 0 bytes, the .SPI file is 134Mb.

But when running the unit tests that loads that dll and runs functions in it, no *.dyn files are generated so the profmerge gives an error message "no .dyn files to merge."

Any hints how to solve this problem or diagnose what is going wrong here? 

I'm using Intel(R) Visual Fortran Compiler XE for applications running on IA-32, Version 12.1.4.325 Build 20120410.
