You mean, gmalloc? How does that come into play?
It seems like data_start and data_size derived from it matter only
when displaying memory usage warnings -- is that correct? If so, why
doesn't this matter when system malloc is used?

The MS-Windows build computes data_start and data_size inside
unexw32.c at dump time -- is that good enough? (I'm asking because
your change doesn't touch the Windows build.)
Thanks.
