[Bug middle-end/41312] New: [4.5 Regression] miscompilation of CP2K at -O3

[jv244 at cam dot ac dot uk]

No testcase other than running CP2K, but the code appears to be miscompiled
(i.e. segfaults) at -O3, while -O2 goes fine. The last known svn version that
was OK was rev. 151454, while the first known failing was 151525. The
miscompiled file is pair_potentials.F 

Any suggestions on how to narrow down the problem?
