------- Comment #91 from jv244 at cam dot ac dot uk 2007-04-24 13:37 -------
current (i.e. this morning) mainline seems to miscompile CP2K (tested current
CVS of CP2K). The code compiled with '-O3 -ftree-vectorize -ffast-math
-march=native' on an opteron segfaults on several regtests. The same code runs
fine with other compilers and gfortran if compiled with '-O0 -g -Wall -Wextra'.
Also, crashes are in several unrelated locations, so it seems something that
might be easy to trigger. Failing testcases include:
/QS/regtest-gpw-1/Ar.inp.out
/QS/regtest-gpw-1/NO2_lsd.inp.out
/QS/regtest-gpw-1/H2O-harris.inp.out
/QS/regtest-gapw/H2O-gapw-gth.inp.out

/QS/regtest-gpw-3/H+.inp.out :

/QS/regtest-gapw/CO.inp.out
/QS/regtest-gapw/CO_xastphh.inp.out
/QS/regtest-gapw/CO_xastpfh.inp.out

/QS/regtest-gapw/CO_xastpxfh.inp.out
/QS/regtest-gapw/CO_xastpval.inp.out
/QS/regtest-gapw/Li-ROKS.inp.out
I'll see if I can reduce the number of optimization options.
