Please submit a full bug report,

When cross_product3_R4_R8 is exported and used directly there is no problem, the
code compiles and runs correctly.

The problem seems to be due to the only clause in this line:
use module_vec3d, only: cross_product
apparently cross_product3_r4_r8 is not loaded into the main program's namespace.
Investigating further ...

I take that last comment back, I had not rebuilt the compiler after removing a
modification.
I'm not sure if this bug also exposes an accepts-invalid issue: changing the
function call to cross_product3_R4_R8 lets the compiler produce a working
executable, even though cross_product3_r4_r8 should not be visible due to the
,ONLY clause, if I understand the standard correctly.

I think what you describe is correct: crossproduct3_R4_R8 should not be visible
in the program's namespace, but the compiler should have enough information to
choose cross_product3_R4_R8 from the argument types even though only
cross_product is used.
In my experience of other Fortran 95 compilers this is the expected behaviour,
but I was not sure if this feature is present in GCC and, if it was, whether it
acts like the C++ virtual keyword rather than statically linking.
The code posted above is an excerpt from a highly-numerical F90 code which I'm
trying to get working on an Itanium. The commercial compiler I have been given
is not up to the task, so I'm exploring other options!
