--- Comment #1 from Arsen Arsenović <arsen at gcc dot gnu.org> ---
current precedent in other toolchains:
- MSVC: rejects alloca entirely in coroutines
- clang: permits alloca in coroutines in many cases. by my crude testing, it
seems to only fail if the size is dynamic and the use of the allocated region
goes over a suspension point. this makes sense, but I'm unsure how involved of
a change it is
for now, best to mark it a 'sorry', as we do with VLAs, rather than produce
bugprone code
