--- Comment #2 from Alexander Monakov <amonakov at gcc dot gnu.org> ---
'volatile' is not viral like that. If 'buf' can be accessed outside of the
abstract machine, it needs to be volatile itself. Alternatively, an empty asm
with a memory clobber, asm("":::"memory"), will imply a possible access to
'buf' via its escaped address.
