FreeBSD localhost 9.2-RELEASE FreeBSD 9.2-RELEASE #0 r255898: Thu Sep 26 22:50:31 UTC 2013 root@bake.isc.freebsd.org:/usr/obj/usr/src/sys/GENERIC amd64
>Description:
The file:
/usr/include/machine/_types.h
reads:
typedef long __int64_t;
typedef unsigned long __uint64_t;
This causes types int64_t and uint64_t be of width 32 when being compiled in the 32-bit mode.
>How-To-Repeat:
$ cat x.c
#include <stdio.h>
#include <stdint.h>
int main(void)
{
printf("%d\n", sizeof(uint64_t));
return 0;
}
$ gcc -m32 -B/usr/lib32 x.c
$ ./a.out
4
>Fix:
These definitions:
typedef long __int64_t;
typedef unsigned long __uint64_t;
should be replaced with something like:
#if defined(__LP64__)
typedef long __int64_t;
typedef unsigned long __uint64_t;
#else
typedef long long __int64_t;
typedef unsigned long long __uint64_t;
#endif
