--- Comment #4 from Richard Biener ---
Indeed this is a case we don't handle as QOI special-case (we accept other
cases of strictly undefined code though).
In this case it is recommended to just do
arglist *p = malloc (sizeof (arglist) + sizeof

--- Comment #3 from Andrew Pinski ---
if you allocated an arglist via malloc (or alloca) and not have a struct which
contained arglist, it would be valid (well GCC would do the correct thing as we
define it as being valid).

A file with small modifications from overoptimized.c, that compiles correctly.
