            Bug ID: 30491
           Summary: mttest failed on aarch64 / OL9
           Product: binutils
           Version: 2.41 (HEAD)
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gprofng
          Assignee: vladimir.mezentsev at oracle dot com
          Reporter: vladimir.mezentsev at oracle dot com
  Target Milestone: ---

This is probably a common stack unwind problem on aarch64 in gprofng.
To easily reproduce the issue, run the gprofng tests on aarch64/OL9:

% cd <BLD>/gprogng
% rm -rf tmpdir
% time make check-extra
...
# of expected failures          3


% cd tmpdir/mttest.-g-O0,-pon
% gp-display-text -ctree test.er/
