Simple example of this issue
I also ran into this issue, though my example is not an inline function I
believe it's the same cause.
I've attached merged-test.tar.bz2, which contains the test, to run just,
$ tar -xjvf merged-test.tar.bz2
$ cd merged-test
$ make test
Testing merged files...

--> http://sourceware.org/bugzilla/attachment.cgi?id=5971
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
Testing merged files...

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.

--- Comment #4 from Doug Evans <xdje42 at gmail dot com> ---
I tested this with trunk, and didn't see the bug, so I'm guessing it's fixed
now.
I don't know which patch fixed it.
[Which isn't to say /m is useful with inlined code,
just that "make test" worked for me.]
