note that these numbers are equivalent to the hello-c++1 from the
attached foo.sh shell script, which brings in a bunch of shared
libraries.  I tried some other sources/linking scenerios to get an
idea of the footprint. (below is the output).

of concern is that of the *-tdep.c files:
amd64, i386, ppc, rs6000, and spu, (at least) use TRY_CATCH or throw_*

and that at least arm uses VEC

I'm not sure how far outside of *-tdep.c this stuff would propagate.


here is the output:
