--- Comment #2 from David Binderman <dcb314 at hotmail dot com> --- I am not sure why the #include is in there. Further reduced code is typedef char int8_t; int8_t c_4, uli_5; unsigned short us_6; func_1() { int uli_9; short ptr_16ptr_11 = &uli_9; for (; us_6 <= 6;) if ((us_6 *= uli_9) < (uli_5 || 0) ?: ((c_4 = us_6) >= us_6) - uli_5) uli_9 = 9; } Flag -O2 required.
