And print in decimal? Without the 0x, it could be ambiguous that it's hex.

I actually prefer them ;-)

Anyway, this looks more like a feature that is for us kernel developers
debugging our own kernels than something that should be added to a distro.
decode_stacktrace.pl can be used for those because distro kernels always
supply debug data that can be downloaded at any time.

I can see this being very useful when debugging something that causes a
crash, as it will save me time from cat'ing the output into
decode_stacktrace.pl after each crash. Although, I can see this having the
same issue as gdb has with static inlined functions.
