I'm posting this for a friend; send replies to me though.

The following C program runs fine on an SE, but refuses to execute
the last line (the printf) on my SE/30. I have tried it with a bare 
System 6.0.3 to no avail. I'm using 3.01 upgraded to 3.02 with the
patch available from sumex-aim.stanford.edu. I'm new to C and LSC;
any help would be appreciated.

#include <stdio.h>
#include <storage.h>

typedef float TRANSFORM[4][4];

TRANSFORM *IDENT, *another;

int alloc(amount)
        int amount;
{
  char *temp;
  char *memptr;

  memptr = (char *) malloc(amount);
  printf("lvalue memptr = %u\n",&memptr);
  printf("rvalue memptr = %u\n",memptr);
  printf("rvalue *memptr = %d\n",*memptr);
  if(memptr == NULL)
    printf("Error: malloc fails\n");
  else {
    temp = memptr;
    while(amount--)
      *temp++ = 0;
  }
  return((int)memptr);
}

main()
{
  IDENT = (TRANSFORM *) alloc(sizeof (TRANSFORM));
  another = (TRANSFORM *) alloc(sizeof (TRANSFORM));
  (*IDENT)[2][2] = 3.1415;
  (*another)[2][2] = 1.234;
  printf("IDENT: %g  another: %g\n",(*IDENT)[2][2],(*another)[2][2]);
}
