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... gdb -x cmds.gdb merged.x GNU gdb (GDB) 7.1-ubuntu Copyright (C) 2010 Free Software Foundation, Inc.
