[Bug middle-end/32450] New: -pg seemingly causes miscompilation

["jv244 at cam dot ac dot uk" <gcc-bugzilla at gcc dot gnu dot org>]

CP2K (see PR 29975) compiles fine with current trunk using 

'-O3 -ffast-math -ftree-vectorize -march=native -funroll-loops'

but the code stops with a bogus error message using

'-O3 -ffast-math -ftree-vectorize -march=native -funroll-loops -pg'

to reproduce see comment 112 in PR 29975 to obtain the code and the example
inputs
