Is it not a 64 bit integer for your compiler?
I'm still interested in the answer to this question.
printing the result of
bit_size(offset)
does give the value of 64
I reckon I had an error in my debug code, I was truncating the output
format, that explains why I'm chasing a gambuzino with this point.
There *is* a bug in OMPI at the moment that we're casting the result back down
to 32 bits. I can give you a patch for that, if you'd like to try it.
I'll get it from svn and try it out. On another note, me thinks with a
derived_data type I nail two with one stroke. This problem and the limitation
of 2GB per core when writing files...
You should be able to get just a patch that you can apply to your v1.6 tarball
here (the trunk patch was different because some filenames have changed between
the v1.6 branch and the trunk):
https://svn.open-mpi.org/trac/ompi/raw-attachment/ticket/3095/fortran-file-int-cast-fix.diff
hmmm... I downloaded the tarball of 1.6, cd to the openmpi-1.6 directory
and tried to apply the patch with
patch < /home/rreis/fortran-file-int-cast-fix.diff
but the result was
rreis@galego: /opt/build/openmpi-1.6
5044.0 $ patch -p1 < /home/rreis/fortran-file-int-cast-fix.diff

so I'm probably doing something wrong here?
