 If I've well understood frame->argv is a value which is in the stack of
 mark_locations_array() (i.e. frame->argv is in (%esp, %esp+end) for
 mark_locations_array).

 Because is_pointer_to_heap() is inlined, gcc must have the
 possibility to store heaps in this address, and this can explain the
 strange comportment

 ruby don't have a problem when this incorrect value don't make reference
 to the stack of mark_locations_array
