You may have simply moved the error to a non-critical region of memory.

Do "strings rclerk | grep TOK" to verify for yourself that none of the
PFTOK* variables exist within it.

Yes, but it will cause memory to be arranged differently than if the
call had not taken place.

Here is the description of a post-5.0.14 fix that is related to calls
and declared variables:

    If you have DECLAREd GLOBAL variables in the automatic and/or the
    input/output table, and then CALL another table which DECLAREs
    addtional GLOBAL variables, such that the total number of such
    variables crosses a multiple-of-32 boundary, and then from within
    the main input/output table execute a non-dash lookup to the main
    file, filePro may crash.

Does this sound like it may be your situation?
