Fix Potential Use-After-Free of Temporary Twine
Fix Potential Use-After-Free of Temporary Twine

Twine is non-owning and the lifetime of the result ends at the semicolon
here unless it is consumed into an owning abstraction. Convert to
a std::string first then insert that into the buffer here.

Not a big deal since this is along a catastrophic error path.
