In addition to what has already be answered, note that your C sample program uses no (significant) RAM. Allocating memory essentially means reserving virtual memory space which is a very lightweight operation and is unrelated to your RAM size.

Beaten...lol. That's what I was going to post. Malloc 1gb of memory does "nothing" until you touch the pages. Replace that statement with, for example, calloc, though, and...well...just go ahead and do it, if you only have 1gb of RAM, get some coffee first, lol.

P.S. "nothing" is a grave over-simplification, but...while it does create page mappings for the process and reserves address space, it doesn't actually back any of the pages until they are touched.
