testcase

The address size of the attached testcase is wrong. It is for i386, so it
should be 4.

Running "llvm-dwarfdump -debug-line test.o" crashes with

lib/DebugInfo/DWARF/DWARFDebugLine.cpp:555: bool
llvm::DWARFDebugLine::LineTable::parse(llvm::DWARFDataExtractor &, uint32_t *,
const llvm::DWARFContext &, const llvm::DWARFUnit *, llvm::raw_ostrea
m *): Assertion `DebugLineData.getAddressSize() == Len - 1' failed.
