## This test shows that llvm-objdump can handle sections with the same address
## when symbols in those sections are referenced. In the past, the section
## picked was non-deterministic, resulting in different symbols being found for
## the section. The test uses YAML for the input, as we need a fully linked ELF
## to reproduce the original failure.
## Two empty sections, one with symbol in, one without.
