[Bug libc/559] New: %I64d is ignored when prepending it with qualifiers

Just take this small program.
--8<------------------------------------------
#include <stdio.h>
int main(int argc, char **argv)
{
printf("%15I64d\n", 10);
return 0;
}
--8<--------------------------------------------
Then compile it using the latest libc (2.3.3). You will see that the %15I64d
statement is simply ignored (you get %15I64d on your console)... As if you do
not provide a qualifier (just %I64d), it IS working (even if printf does not
take care of your qualifier).
Tested on SuSE 9.1 and 9.2.
The problem is that if you have a more complex printf format string (like "%
15I64d: %s" your string argument will be your big integer and you will get a
beautiful segfault ;-) (nice isn't it ?)
