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

# CHECK-NOT: .discard
