Obviously the commit did not introduce an unused variable, but instead
made another variable take its place as the function's return value.  In
an assert-enabled build it was used by an assert, which is why I didn't
notice the problem.  I removed the assert and the variable so this
should be fixed now.

Thanks for reporting.
