Re: [PATCH 0/2] addr2line: new option -n to add a newline at the end

I am sorry - I totally missed this patch submission. :-(

I have to say that I am kind of with Jan on this one - it seems like
a lot of effort to fix a small problem.  Isn't there an easier way
that would not involve patching addr2line ?  For example if you use
the -a/--addresses option then each decoded address will be prefixed
with a line containing a simple hex number.  This would allow a consumer
of addr2line's output to detect the start of each decoded address.

I am not sure what you are getting at here.  Are you saying that addr2line
can get stuck and so a timeout is needed in order to be to distinguish between
addr2line being slow and addr2line being stuck ?  If so then this sounds
like a more serious problem that needs to be addressed by something other
than just adding a blank line to the output.
