[Click] Bug in latest CVS?

[Nicholas Weaver]

Attached is a click file which works fine on a few week old checkout by CVS,
but fails on the latest checkout with:

click: ../include/click/vector.hh:45: T& Vector<T>::operator[](int) [with T = String]: Assertion `i>=0 && i<_n' failed.


The error appears to be in the dasabe lookup:

The GDB backtrace:

(gdb) run flowlist.click
Starting program: /da/nweaver/reset_detect/click/userlevel/click flowlist.click
click: ../include/click/vector.hh:45: T& Vector<T>::operator[](int) [with T = String]: Assertion `i>=0 && i<_n' failed.
