Package: libc0.2-dbg
Version: 2.0.110-0.1
I am forwarding a message from Roland McGrath, accompanied with my own
comments. It's really his reported bug, but he doesn't have time to
learn the BTS, so I'm submitting it.

Yes, the Linux version also includes debugging symbols.

I have to agree with Roland here on both points. Has there been
thought to creating a separate libc-profile (without debugging
symbols), and/or a libc-dbg without symbols (but with a frame
pointer)?
