Ah, yep!
pragma(LDC_alloca) void* alloca(size_t);
This appears to work with ldc. It would be nice if there was a
way to do this with dmd/other compilers as well though. If it
were up to me I'd have alloca defined by the language standard
and every compiler would have to provide an implementation like
this. At the very least I'd like to have an alloca that works
with dmd, as I want to do debug builds with dmd and release
builds with ldc.
