--- Comment #1 from H.J. Lu <hjl.tools at gmail dot com> ---
We should warn:
---
struct a { int i; } __attribute__((__packed__));
void c (struct a **);
void d (const struct a *b) { c ((struct a **) b); }
--
But should we warn
--
struct a { } __attribute__((__packed__));
void c (struct a **);
void d (const struct a *b) { c ((struct a **) b); }
--
in C? Since "struct a" is empty, can we ever generate unaligned access
to an empty structure?
