No, I don't want a work-around. You should add something like this

if (_get_bof_handler != profiler_bof)
  throw UsageError, "Another process grabbed the bof handler. Please
    pay attention that stckcheck is not active";

to profile_end() or

if (_get_bof_handler != NULL and _get_bof_handler != stkcheck_bof)
  throw UsageError, "Another bof handler is active. You can't use
    stkcheck and profiler at the same time";

to enable_stack_check(). It took me some time to find out that stkcheck
is the cause of cluttered profiling output.

Bye, Jörg.
