My guess is that `count' refers to uninitialized memory. The test program
below compiles and runs without incident, even when compiling Electric
Fence and setting EF_ALIGNMENT=0.
#include <stdio.h>
#include <dirent.h>
int main(void)
{
int *count;
struct dirent dir_ent;
*count = 1;
fprintf(stdout, "sizeof(dir_ent) * (*count) = %d\n",
sizeof(dir_ent) * (*count));
return 0;
}
