Comment #1 on issue 377 by [email protected]: unknown-crash with
annotate_contiguous_container
https://code.google.com/p/address-sanitizer/issues/detail?id=377
Small mistake in the provided code, doesn't affect the result.
#include <stdio.h>
#include <stdint.h>
// Not 8-aligned
#define SIZ 132
struct foo {
uint32_t a;
char buf[SIZ] __attribute ((aligned(8)));
};
void setup_stack() {
struct foo blah1;
struct foo blah2;
struct foo blah3;
printf("%p %p %p\n", &blah1, &blah2, &blah3);
char *lol = &(blah2.buf);
printf("lol = %p\n", lol);
__sanitizer_annotate_contiguous_container(lol, lol+SIZ, lol+SIZ, lol+0);
__sanitizer_annotate_contiguous_container(lol, lol+SIZ, lol+0, lol+SIZ);
printf("setup_stack done\n");
}
void crash() {
volatile char buf[1024];
printf("buf = %p\n", buf);
int i;
for (i = 0; i < 1024; i++) {
printf("%d\n", buf[i]);
}
}
int main(int argc, char *argv[]) {
setup_stack();
crash();
return 0;
}
