Additional info:

By "always reproducible, I mean with the attached code, not with any code.

The attached example contains a fairly large amount of code.  The execution path
is actually quite short, however this bug seems to be highly location-dependent.
 Deleting any of the other object files that are included causes the bug to not
be exercised.

The problem occurs with gcc-c++-2.96-98. The Valhalla compiler gcc-c++-2.96-110
does not exhibit the problem on this code, however I did not see any indication
that a problem like this was fixed.  gcc-2.95.3 also does not exhibit the
problem.  It is possible that other differences in these compilers move things
around so that the bug is simply not exercised.
