What environment are you using? I presume you have no MMU, because in a
system with an MMU physical memory generally isn't allocated until the page
is touched. (And zeroed out memory pages are multiple copy-on-write mappings
of the zero page.)
That said, if you build a debug version (it's in the menuconfig options) and
run "nm --size-sort" on the result, it should tell you who the biggest
offenders are. Then you can grep the source for the symbols...
