------- Comment #16 from dominiq at lps dot ens dot fr 2009-08-25 21:25 -------
After some discussion on IRC with Tobias Schlüter, it seems that the problem
comes from bad optimizations that are broken by chance with the original code.
Commenting line 139:
WRITE (6,*) i , spx(i) , epx(i) , NPX(i)
is enough to go from ~8.5s to ~10.2s without having nothing to do with
-fwhole-file or Tobias' patch.
