# Test reading an ExceptionRecord which is referenced in different ways:
# - Relocation against base of .xdata record, immediate offset in .pdata
# (what LLVM produces)
# - Relocation against symbol in .xdata, no immediate offset in .pdata
# (what MSVC produces)
# - Combination of the two above (unlikely to occur in the wild, but for
# testing the consistency of the code)
