Hi Mark,

Keep in mind that the stack trace could be corrupted. You might want to 
run with a trivial subroutine for testing.

In addition to that it's always a good idea to write a short test 
program that calls the subroutine function with some test values. You 
can run this test program with

valgrind --tool=memcheck <your_test_program>

to see if it is writing to memory it should not write to.

Regards,

Martin
