Recently I noted that the loaded (ld) allocates memory that I've

I wrote a simple short C program that exhibits the same problem (or
perhaps it's a new feature):
gcc -o ldhog ldhog.c
will (depending how much memory you have, and how big N is) sit there
for quite some time.This version uses a little over 500MB.
In previous versions of ld, this was not a problem, but somehow now
it is. Perhaps this is a bug fixed in Ubuntu 11 ?
I am running this on 10.10.
AFAIK, the array is uninitilized data, and indeed, the size command
shows up with 500+ MB in the .bss section of the executable.
So it's beyond me why ld should allocate that space and do something
Anybody have an idea what's going on here?
one reply to my post. The compile (link) option
appears to be doing the job. I also confirmed that Ubuntu 11.04
still has the same "issue", thogh a newer version
