Not quite.  It's normally the beginning of the heap, after the bss section.

That said, it looks like start_brk is a dead variable.  It's written only by the
FLAT loader, and nothing at all reads it, except for this debugging dump.

The "real" value is the "brk" variable, which is indeed set to a plausible 
looking value.
