4Subject: [PATCH] _bfd_clear_contents bounds checking
5
6This PR shows a fuzzed binary triggering a segfault via a bad
7relocation in .debug_line. It turns out that unlike normal
8relocations applied to a section, the linker applies those with
9symbols from discarded sections via _bfd_clear_contents without
10checking that the relocation is within the section bounds. The same
11thing now happens when reading debug sections since commit
12a4cd947aca23, the PR23425 fix.
