Please I don't want to annoy you but the instructions to file a bug are really
hard to follow and lengthy. I haven't been able to produce the "*.i* file, but
just the ".s" one. Please mail me if you want me to send you the whole package
or else give me other instructions.

Thank you.

Those instrunctions are more for C/C++ bug filing.
Does the code use modules?
If not can you just attach dynamic.f if it is open source?

I could attach the 'dynamic.f' file if you tell me how (or is it just to
cut-and-paste it?). The file is NOT open source but is free for academic use.
It DOES use modules.

Luis,

You can email me the file at sgk@troutmask.apl.washington.edu.
I'll extract a testcase if the failure occurs on my systems.

Just a quick note.  dynamic.f will compile without optimization.
I can reproduce the problem.  Now to reduce it to something managable.

Reduced testcase


module current
   integer, save :: ndim
   real, save :: kv(3,3)
end module current

subroutine dynamic

   use current

   implicit none

   real :: kvf(3,3)

   if (ndim .eq. 3) then
      call kvector3Df(kvf)
   else
      kvf(1:3,1:3) = kv(1:3,1:3)
   end if

end subroutine dynamic

Further reduction is possible.

subroutine dynamic(ndim, kv)
   implicit none
   integer :: ndim
   real :: kvf(3,3), kv(3,3)
   if (ndim .eq. 3) then
      call kvector3Df(kvf)
   else
      kvf(1:3,1:3) = kv(1:3,1:3)
   end if
end subroutine dynamic
