Bug ID: 111398
Summary: GCC should warn if a struct with flexible array member
is declared static or onstack
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: tg at mirbsd dot org
Target Milestone: ---
If I have (-std=c99 and up) a…
struct foo {
size_t len;
char buf[];
};
… then I would like to be warned (at least with -Wextra or something) if I do
either of…
static struct foo a; // this
struct foo b; // this
extern struct foo x; // and probably even this!
void bla(void) {
static struct foo c; // this
struct foo d; // and this
}
(Probably the same for GCC’s char buf[0]; extension.)
