I like the idea of simpler and cleaner, but your patch's implementations
of build_local_vector and build_local_string use alloca expressions as
function arguments, and the GNU API for alloca doesn't support that.
You can work around the problem by using statement expressions, falling
back on plain Fmake_vector and/or make_string for compilers that don't
support statement expressions.
To address Stefan's concern about alloca-allocated thingies escaping to
Elisp, is there some way you can include a runtime test for that, when
checking is enabled? It wouldn't have to catch every escapee, just a
high percentage of them.
