Another example of this issue.

I have another test that is failing I believe for the same underlying cause,
though the failure is slightly different in this case. In this test a single
merged.c file includes foo.c and bar.c. If I try to disassemble with source
code functions from foo.c or bar.c then no source lines are found/printed.

To run the test,

$ tar -xjvf merged-test-2.tar.bz2
$ cd merged-test-2
$ make test

In the first case ("Testing merged files...") the disassembly for "main" and
"function" contain no source lines. In the second case ("Testing unmerged
files...") the disassembly for "main" and "function" do contain the source
lines.
