            Bug ID: 29539
           Summary: LD_TRACE_LOADED_OBJECTS changed how vDSO library are
                    printed
           Product: glibc
           Version: 2.36
            Status: NEW
          Severity: normal
          Priority: P2
         Component: libc

  Target Milestone: ---

The d7703d3176d225d5743b21811d888619eba39e82 changed on how vDSO like
dependencies are printed, instead of just the name and address it follows o=
ther
libraries mode and print 'name =3D> path'.

Unfortunately, this broke some ldd consumer that uses the output to filter =
out
the program's dependencies.  For instance CMake bundleutilities module [1],
where GetPrequirite uses the regex to filter out 'name =3D> path' [2].
