Re: lib/59652: DNS utilities core dump in -current
More analysis shows me it's a ld.elf_so bug that means the data isn't
aligned correctly relative to the struct tcb_tls for__HAVE_TLS_VARIANT_I
I didn't check __HAVE_TLS_VARIANT_II yet.
Here's a little test program that fails.
#include <inttypes.h>
#include <assert.h>
#define ALIGNMENT 64
#define MAGIC1 0xaa55aa55aa55aa55
#define MAGIC2 0xc0ffeeeeeeeeeeee
#define MAGIC3 0xff00ff00ff00ff00
__thread
struct {
uint64_t magic1;
uint64_t magic2 __attribute__((aligned(ALIGNMENT)));
uint64_t magic3;
} tls_data = {
.magic1 = MAGIC1,
.magic2 = MAGIC2,
.magic3 = MAGIC3,
};
int
main()
{
assert(tls_data.magic1 == MAGIC1);
assert(tls_data.magic2 == MAGIC2);
assert(tls_data.magic3 == MAGIC3);
}
