  * 5e63739 2022-07-18 | Add bazel support for iOS arm64 simulator (#105) (HEAD -> master, origin/master, origin/HEAD) [Keith 
  Smiley]

• Reproduce

  
  #include <stdio.h>
  #include "cpuinfo.h"

int main() { cpuinfo_initialize();

const cpuinfo_core* core = cpuinfo_get_current_core();
printf("core is %p\n", core);

cpuinfo_deinitialize();

return 0;

}

- Expected behaviour
  The print value of `core` should be not "0x0"
- The actual output

core is 0x0
