Comment 2 for bug 493278

It's possible this size change traces back to the following Debian changelog entry:

erlang (1:13.b.1-dfsg-6) unstable; urgency=low

  * Restored debug info in beam files for default build. It's better to use
    more space than to ship broken modules (debugger, dialyzer). The patch
    is simply commented out in debian/patches/series, so if someone has to
    strip debug info, he can simply uncomment it.
