libstc++ uses __builtin_alloca in several places:
config/local/gnu/codecvt_members.cc
include/ext/codecvt_specializations.h
include/ext/vstring.cc
include/bits/locale_facets.tcc
include/bits/ostream.tcc
include/bits/fstream.cc
include/std/std_valarray.h
src/valarray-inst.cc
These have data-dependent sizes with no obvious limit, which does not mix well
with threads and small stacks.
