## 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.
