Unfortunately, we had this exact case 2 days ago with a spirit::qi bug, 
induced by an uninitalised variable and a weird edge case. But i would 
agree that confirmation of this can only be given by a proper valgrind 
run( or a similar tool) to record any weird memory issues.

If the testprogram succeeds without valgrind finding anything, do the 
same with your full program. compile in debug and run valgrind.

Best,
