 ## These test checks that llvm-objdump will not crash with malformed archive
 ## files. The check line is not all that important but the bug fixes to
 ## make sure llvm-objdump is robust is what matters.

 ## Check we report an error when unable to read the size field on an archive as an integer.
 ## Check two cases: a) the first member is valid, but the second is not, and b) both are invalid.
