The correct debug info cannot be found. The first attempted location was inside
the ld-2.12.2.so itself:
> --1688-- Considering /lib/ld-2.12.2.so ..
> --1688-- .. CRC mismatch (computed ebfc32b7 wanted 596e7f90)
but the debuginfo was not there. (Perhaps it was empty, such as removed
by "strip" or "ld -S".)
The second attempted location was:
> --1688-- Considering /lib/.debug/ld-2.12.2.so ..
> --1688-- .. CRC mismatch (computed 4cc18107 wanted 596e7f90)
and that file does have debuginfo, but it does not match.
The third attempted location was (from the strace.out):
1412 open("/usr/lib/debug/lib/ld-2.12.2.so", O_RDONLY) = -1 ENOENT (No such
file or directory)
but that file was not found.
So /lib/ld-2.12.2.so does not match /lib/.debug/ld-2.12.2.so.
Either the wrong version was installed in the first place, or an update
was performed on one file but not the other. Check the dates via "ls -l"
(and follow symlinks until you get to regular files.)
They should be close to each other: no more than about a minute apart.
Try a re-install of *both* files.
