Joost VandeVondele has posted this morning 15 PR from #30869 to #30883.
On OSX 10.3.9, gfortran 4.3.0 20070216 + patch for PR #30400 gives an
error while they compile and run without problem with g95 and xlf, but
for #30874 which gives the right result and #30881 which gives an ICE.

I don't know f90 and above well enough to comment about the validity of 
the codes.
