strip: Files with symbols referring to non-existing sections are illformed
|
||
|
|
|
||
|
|
The check added in commit 4540ea98c "strip: Fix check test for SHN_XINDEX
|
||
|
|
symbol" was not complete. The (extended) section index should also exist.
|
||
|
|
If it doesn't exist, mark the file as illformed.
