no, how about trying my suggestion?
~ % cat t.c
#include <stdio.h>
int main(void) {
int x;
printf("enter number of bytes to allocate");
scanf("%d", &x);
printf("allocating %d bytes...\n", x);
if (malloc(x * sizeof(char)) == NULL)
perror("malloc");
else
printf("ok.\n");
}

ok.
~ % ./a.out
enter number of bytes to allocate513000
allocating 513000 bytes...
malloc: Cannot allocate memory
If smbd can't handle running out of memory then that's a smbd bug.
