On my system, debugging a natively-compiled Emacs takes GDB just a bit
more that debugging non-native one: 120MB vs 100MB. The first number
is similar to yours, so I wonder how come the second number is so much
different on you're system. Is that with "emacs -Q" run under a
debugger? In any case, a full Emacs version running for 10 days under
GDB causes GDB to have just 200MB of memory here, which is a far cry
from your 2.5GB. I wonder why such a large difference.

Yes, but regenerating the *.eln files takes a few minutes, so why is
that such a big problem?

Look closer at the build process, something probably failed there, so
the build didn't complete successfully.
