           Summary: Block Data initialisation only from first shared library
                    of a common block
           Product: gcc
           Version: 3.2.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: s dot blackett at auckland dot ac dot nz
                CC: gcc-bugs at gcc dot gnu dot org
  GCC host triplet: i586-mandrake-linux-gnu

When several shared libraries using the same common block are linked together
then only block data initialisation from the first library is used.  The link
changes the block data symbol to .data in each case and the final link seems to
just use the first one.
The enclosed tar builds three executables, test_block_data which has the BLOCK
DATA in the first library and so succeeds, test_block_data2 which has the same
libraries linked in the reverse order and fails and test_block_data3 which links
the objects without the libraries and so succeeds.
