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

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?
