Similar to unsigned bounds propagation fix signed bounds.
The 'Fixes' tag is a hint. There is no security bug here.
The verifier was too conservative.

The change looks good. Should a new test_verifier test be added
to exercise the new change?
I think manually string comparing output the way VERBOSE_ACCEPT is doing
is an overkill here.
The real test case in .c will take some time to craft.
Okay. Sounds good to me.
