Paul,

I'm seeing failures of the testcase proc_ptr_comp_45.f90 on my
i686-pc-linux-gnu box.  Manually compiling the test with -mfpmath=sse
makes the test pass.

Alternatively, replacing the conditions by:

  if (abs (template%obs1_int (arg) - cos (arg)) > 2.e-15) call abort

and

  if (abs (object%obs1_int (arg) - cos (arg)) > 2.e-15) call abort

works for me.

Honza, can you double check this? Could be a regression. I can reproduce the
error, in any case.
