# Test handling of object files that have duplicate sections. This is legal,

# according to the System V ABI (Edition 4.1); see 4-20 where it says:
|
|
#
|
|
# Section names with a dot (.) prefix are reserved for the system,
|
|
# although applications may use these sections if their existing
|
|
# meanings are satisfactory. ... **An object file may have more than
|
|
# one section with the same name.**
