```c
#include <float.h>
#include <stdlib.h>
#include <time.h>
#include <stdatomic.h>
#include <complex.h>
#include <limits.h>
int main(void) {
char buffer[50];
double d_value = 3.1415926535;
strfromd(buffer, sizeof(buffer), "%.5f", d_value);
time_t now = 1234567890;
struct tm tm_data;
struct tm* lt = localtime_r(&now, &tm_data);
atomic_int counter = 42;
atomic_fetch_add(&counter, 10);
_BitInt(BITINT_MAXWIDTH) big_bitint = (_BitInt(BITINT_MAXWIDTH))1 << (BITINT_MAXWIDTH - 1);
double complex z = 1.0 + 2.0*I;
unsigned int u_val = UINT_WIDTH;
return 0;
}
```
This program will timeout when using the option -std=c2x on the latest trunk version of llvm, but in GCC
```
Killed - processing time exceeded
Program terminated with signal: SIGKILL
Compiler returned: 143
