stack corruption detected (-fstack-protector)

[Andrey Alekseenko]

Have a nice day!

I'm trying to debug native crash with stack corruption.

The complete stack trace has much more entries and I've a suggestion that the reason is stack overflow.

I've tried to increase stack size creating new thread using boost::thread with stack_size attribute set and using pthread_create with pthread_attr_setstack... but with no luck. Looks like these API for setting stack size do not work or I'm doing something wrong...

What is the right way to change native thread stack size in NDK?

Or any other advices?

Code of h323.cpp looks like (it is legacy and generated by some tool, and it uses recursion alot):

static void P_TransportAddress(per_data_t *pd) {

   DBGX; static const per_choice_t TransportAddress_choice[] = {
      { 0, ASN1_EXT_ROOT, P_TransportAddress_ipAddress }, /* ipAddress */
      { 1, ASN1_EXT_ROOT, P_TransportAddress_ipSourceRoute }, /* ipSourceRoute */
      { 2, ASN1_EXT_ROOT, P_TransportAddress_ipxAddress }, /* ipxAddress */
      { 3, ASN1_EXT_ROOT, P_TransportAddress_ip6Address }, /* ip6Address */
      { 4, ASN1_EXT_ROOT, P_OCTET_STRING_16 }, /* netBios */
      { 5, ASN1_EXT_ROOT, P_OCTET_STRING_1_20 }, /* nsap */
      { 6, ASN1_EXT_ROOT, P_NonStandardParameter }, /* nonStandardAddress */
          { 0, 0, NULL }
     };

   per_choice(pd, TransportAddress_choice);
}

I've found the problem:

There was a bug like that:

void a(unsigned long* ptr) { *ptr = 0; }

void b() {

 int x;

 a(&x);

}

Is this solved?
