Incorrect Listing Output with .lcomm

[Tracy Kuhrt <Tracy dot Kuhrt at microchip dot com>]

Given the source:
        .data

        .lcomm a, 1

        .lcomm b, 50
        .lcomm c, 1

        .text
foo:
        .lcomm d, 1
        .lcomm e, 10
        .lcomm f, 20
        .lcomm g, 1
        .end


binutils configured for a target of sparc-sun-coff generates the
following listing file in which the line numbers listed under DEFINED
SYMBOLS do not match the line numbers where the symbol was defined.
Also, the very first symbol 'a', does not have an associated file and
line number.

Any ideas where I should start looking?
