I'm having a problem porting source code from a unix machine to 
my mac.  It seems that once I work out bugs caused by the difference
in default integer sizes (2bytes mac, 4bytes unix) I'm  having 
weird problems with malloc.  For example, the following code
doesn't work quite (er, at all) right:

int *y;
<printf *y gives garbage>
y = (int *) malloc (sizeof(int));
*y = 5;
<printf *y STILL gives garbage>

If I replace the malloc with NewPtr, things work fine, but it
doesn't seem right that the brilliant people at symantec would
develop wonderful user interfaces and debugging tools and forget
to write a working malloc().

What's up?  I've repeated this problem on several machines.

Thanks for any help,
George John
