I allowed me to apply the following change: http://gcc.gnu.org/viewcvs?view=revision&revision=182109
Assumptions like sizeof(int)==4 or sizeof(void*)==4 are the most frequent cause for annoying false FAILing C test cases. Besides that: Why are there new test cases in gcc.c-torture? As far as I remember that place is deprecated and the preferred place for new C tests like this is gcc.dg?
