--- Comment #1 from David Blaikie <dblaikie at gmail.com> ---
This is considered an acceptable false positive given the true positives it
allows.

This code can be rewritten to avoid the warning. Replace this:

foo false_positive_unsused_variable(b,argc);

with this:

foo(b,argc);

Since you don't need the named variable (it has no work to do in its dtor) &
just want the ctor side effects.
