#252 Problem printing unsigned long longs

[Stephan T. Lavavej]

I am using gcc 3.2:

C:\Temp>gcc --version
gcc (GCC) 3.2 (mingw special 20020817-1)
Copyright (C) 2002 Free Software Foundation, Inc.
This is free software; see the source for copying

languages=f77,c++,objc,ada --disable-win32-registry --
disable-shared
Thread model: win32
gcc version 3.2 (mingw special 20020817-1)

My operating system is Windows XP Pro SP-1.

This trivial C program demonstrates the bug:

#include <stdio.h>

int main(void) {
printf("Lines should be identical:\n");
printf("A4506CEBDE82BDE9\n");
printf("%016llX\n", 0xA4506CEBDE82BDE9ULL);
return 0;
}

It outputs:

C:\Temp>bug
Lines should be identical:
A4506CEBDE82BDE9
00000000DE82BDE9

The error also occurs in C++ programs.

I initially experienced the bug in a program that printed
eight unsigned long longs; it worked properly when
compiled with DJGPP but crashed when compiled with
MinGW.

This test case triggers the crash:
#include <stdio.h>

int main(void) {
printf("Second and third lines should be identical to
first, followed by foo:\n");
printf("A4506CEBDE82BDE9\n");
printf("%016llX\n%016llX\n%s\n",
0xA4506CEBDE82BDE9ULL,
0xA4506CEBDE82BDE9ULL, "foo");
return 0;
}

It looks like I've duplicated a bug report submitted mere hours
before mine; I apologize.

However, it is definitely a bug. The ll length modifier is
definitely C99; see section 7.19.6.1 of the Standard.
