perf / DWARF bug - is this something to do with the new DWARF format?

[Richard W.M. Jones]

https://bugzilla.redhat.com/show_bug.cgi?id=1963865

I can't get stack traces using --call-graph=dwarf information working
in Rawhide at the moment. It seems as if perf doesn't understand the
new debuginfo information.

I find this whole area to be incredibly confusing and opaque. For
example, how do I find out what dwarf version was used to generate the
debuginfo and what version perf understands?

But my main question is: Is there some simple change to perf that is
needed to fix this? Or is it user error?

Rich.

Surely a question for the Test list?
