These tests call the library function, so whatever goes
wrong here probably needs to be fixed in the
generated functions as well.

Correction: this occurs only when a function takes no arguments but alloc_size
is used.

When declaring a function with __attribute__((alloc_size(n))), gcc segfaults if
n exceeds the number of arguments to the function.
