Sorry, the original testcase contains a non-std header from csmith.
Updated testcase:

#include "stdint.h"
uint16_t g_30, g_65;
uint16_t *g_54;
uint32_t func_59(uint32_t);
int32_t func_1() {
  for (; g_30 != 7; ++g_30)
    func_59(0);
}

uint32_t func_59(uint32_t p_60) {
  for (; g_65; ++g_65)
    for (p_60 = 0; p_60 <= 50; p_60 = p_60 + 2) {
      uint16_t **l_77 = &g_54;
      if (g_30)
        *l_77 = 0;
    }
}
