[Bug tree-optimization/17928] New: ICE involving 'goto' to jump into loop

["bryner at brianryner dot com" <gcc-bugzilla at gcc dot gnu dot org>]

The testcase I'm going to attach gives an ICE when you compile like this:

gcc -Os -c -o gcc-prdtoa-testcase.o gcc-prdtoa-testcase.c

problem occurs with -Os but _not_ with -O0, -O1, -O2, or -O3.  Looks like some
sort of infinite recursion with analyze_scaler_evolution().  This was as reduced
as I could get the testcase.

compiler version:
$ gcc -v
