--- Comment #2 from Tom Tromey <tromey at sourceware dot org> ---
"maint space 1" reports a big difference alright.

Good:
(gdb) print StartOfUserCode
$1 =3D {void (void)} 0x866d8 <StartOfUserCode()>
Space used: 208310272 (+204247040 for this command)

Bad:
(gdb) print StartOfUserCode
Space used: 5955563520 (+5949935616 for this command)
No symbol "StartOfUserCode" in current context.


For me it also fails, but that's because this symbol isn't
defined in the release ELF.

gdb seems to be expanding every CU here.

Agreed, though I didn't dig into where it all goes.
It definitely seems excessive given that the DWARF
only seems to be 240k or so.
