The code in main_loop is also supposed to catch execution exceptions.
Is that not happening for you in this case?  If you also use the gdb
command "catch catch" to stop when the exception is caught, does it
show you that this exception is caught somewhere?  If you continue on
from there, do you generate a segfault at some point?  Is there an
exception that is thrown but not caught?
