            Bug ID: 30195
           Summary: [display text] Source code location can not be found
           Product: binutils
           Version: 2.40
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gprofng
          Assignee: vladimir.mezentsev at oracle dot com
          Reporter: ruud.vanderpas at oracle dot com
  Target Milestone: ---

As the log of my session shown below shows, gprofng cannot find the location of
a source file, but the code has been compiled with -g.

This error has been observed using gcc 11 on Oracle Linux 9.
