Testcase where loop distribution enabled makes run of binary forever
Compilation with CFLAGS="-O2" and running of testcase is ok (it finish).
Compilation with CLFLAGS="-O2 -ftree-loop-distribution" and running testcase
makes it run forever (last loop cycles). Inlined loop from free_alt_states is
wrongly distributed.
