/*
 *  When 'ctx' has a catch point (safe call) and the safe call runs eval()
 *  in a different thread which throws an error, there is valgrind whine
 *  about interrupt_counter handling.  Other than the valgrind whine (which
 *  is quite harmless) the test case passes.
 *
 *  This happens both when pushing a thread with reused globals and fresh
 *  independent globals.
