Hi,
I am seeing crash when I run an application using %f in printf on X64
platform. Please find the code and .inf file content below.
Can anyone help me in this regard?

#include <stdio.h>
#include <wchar.h>
#include <stdlib.h>
#include <Uefi.h>
#include <Library/UefiLib.h>
#include <Library/ShellCEntryLib.h>
int
main (
IN int Argc,
IN char **Argv
)
{
double temp = 0.0319;
wchar_t *str;
str = (wchar_t *) malloc(10);
if (NULL != str) {
printf("This is test\n");
printf("temp (f) = %f, temp (e) = %e\n", temp, temp);
printf("temp (d) = %d, temp (x) = 0x%x\n", (int)temp, (int)temp);
swprintf(str, 5, L"%0.2f", temp);
wprintf(L"str (ls) = %ls\n", (const wchar_t *)str);
printf("str (ls) = %ls, str (s) = %s, size (f) = %f\n", str, (char *)str,
temp);
}
else {
printf("str malloc failed\n");
}
return(0);
}
