# Check address lookup works correctly in the presence of type units.
# Specifically check that we don't use the line table pointed to by the
# DW_AT_stmt_list of the type unit (which used only for the file names) to
# compute address range for the type unit as type units don't describe any
# addresses. The addresses should always resolve to the relevant compile units.
