Rubbish. Works perfectly.

cat  test.c <<EOF
#include <stdlib.h>
#define QEMU_NEW(type) (type*)malloc(sizeof(type))
typedef struct { int x; } foo;
typedef struct { double y; } bar;
int main(int argc, char **argv)
{
  foo *ptr = QEMU_NEW(bar);
  return 0;
}
EOF
gcc test.c
test.c: In function ‘main’:
test.c:7: initialization from incompatible pointer type
