Tobias,
Nothing - I have just updated to FC8 and blew all my nice set-up to
pieces. This is the first time that Fedora has let me down. I will be
operational

The patch in comment #12 works as advertised without regression in 32 and 64
bit modes on ppc/Intel and my favourite platform.
Thanks for the test. I have been through several variants

This is a most peculiar bug, which has nothing to do with allocatability or
temporariness. The result variables of the functions 'get_numbr' and
'get_nfirst' are REAL(mp), whereas they are assigned to INTEGER
--- Comment #12 from pault at gcc dot gnu dot org 2008-01-01 17:23 ---
Ah! I feel a light bulb moment coming on.
The type mismatch necessitates the use of the internal real to integer
conversion function, which in its turn checks the interface with 'get_nfirst'.
Being a formal

Jon:
If the LHS is a dynamically allocated array, attempting
to assign the array of values from the functions causes an ICE.

I can not reproduce the valgrind error, but ...

end module blk1_mod
... the ICE goes away if 'numclusters' is defined as a parameter.

code compiles fine with NAG and g95, the line at the segfault looks OK.
