## The test checks that llvm-dwp avoids an out of bound access when there is
|
|
## an unknown section identifier in an index section. Without the fix, the test
|
|
## failed when LLVM is built with UBSan.
|
|
## Note that additional sections (.debug_abbrev.dwo, .debug_info.dwo, and
|
|
## .debug_types.dwo) are required to reach the test points in the code.
