   7 ## Test shows that we do not crash after discarding the .discard.foo with -r.
   8 ## Previously it happened because of 2 reasons:
   9 ## 1) .rela.discard.foo was not handled properly and was not discarded.
  10 ##    Remaining reference was invalid and caused the crash.
  11 ## 2) Third-party section .debug_info referencing discarded section
  12 ##    did not handle this case properly and tried to apply the
  13 ##    relocation instead of ignoring it.
