Commit ecd6cf800b63704be73fb264c3f5b6e0dafc068d by marks in OpenSolaris
at Tue Jun 26 07:44:24 2007 -0700 introduced a bug where we fail to call
`va_end()` before returning.
The man page for va_start() says:
"Each invocation of va_start() must be matched by a corresponding
invocation of va_end() in the same function."
Coverity complained about this.
