Hmmm, I can reproduce this with gcc-20000617 on i686-pc-linux-gnu;
without -fdebug-kludge there is no problem.

Note that you do not need -fdebug-kludge anymore, as this version of the
compiler supports normal debugging information for COMMON items.

However, I'll try to investigate which combinations of -g and
-fdebug-kludge cause problems, as they - at the very least - have to be
documented.

Thanks for your bug report,
