Hi Yujie, Randy, and Geert,

Thanks for reporting this.  It was indeed a bug in how some
non-Boolean config options get set when kismet generates .config files
for bug validation.  kismet v4.5.1 now includes the fix, and the
symbol value warning no longer appears when I replicate with Philip
and Yujie's steps.

The unmet dependency bug for SM_GCC_8550, however, still appears and
looks to be to be genuine.  Jagadeesh's patch seems to fix that.

Best,
Paul
