What were you trying to do that didn't work?

scl enable gcc-toolset-13 'gcc -fsanitize=address main.c'

// main.c

#include <stddef.h>
#include <stdio.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <arpa/inet.h>
#include <netdb.h>int main() {
  struct addrinfo *servinfo = NULL;
  struct addrinfo hints = {0};
  const char* hostname = "www.ibm.com";
  const char* ip_address = NULL;  hints.ai_family = AF_INET;
  hints.ai_socktype = SOCK_STREAM;
  hints.ai_flags = AI_PASSIVE;
  hints.ai_protocol = IPPROTO_TCP;  int rc = getaddrinfo(hostname, NULL, &hints, &servinfo);
  printf("getaddrinfo -> %d\n", rc);
  if (rc == 0) {
    struct sockaddr_in *ipv4 = (struct sockaddr_in *)servinfo->ai_addr;
    ip_address = inet_ntoa(ipv4->sin_addr);
    printf("%s resolves to %s\n", hostname, ip_address);
  }}}{{  freeaddrinfo(servinfo);  return 0;
}

Please provide the package NVR for which bug is seen:

How reproducible:

reproduced on two different RHEL 8.9 machines.

Steps to reproduce

1. scl enable gcc-toolset-13 'gcc -fsanitize=address main.c' && ./a.out

Expected results

$ ./a.out }}{{getaddrinfo -> 0

www.ibm.com resolves to 184.26.226.231

Actual results
