For now, all I can tell is: my Fortran-based project gives acceptable results
with r137251 (FCFLAGS="-O2"), but r137252 produces strange output that can,
numerically, not be justified. For FCFLAGS="-O1", both revisions seem to work.

Can't provide a testcase for now as I'm not sure where I should start looking.
Pointers welcome :)
