Date: Mon, 10 Oct 2011 12:43:00 -0000 [thread overview] Message-ID: <bug-12444-4717-mivJNObIHf@http.sourceware.org/bugzilla/> (raw) In-Reply-To: <bug-12444-4717@http.sourceware.org/bugzilla/> http://sourceware.org/bugzilla/show_bug.cgi?id=12444 --- Comment #3 from Andrew Burgess <aburgess at broadcom dot com> 2011-10-10 12:42:43 UTC --- Created attachment 5971 --> 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... gdb -x cmds.gdb merged.x GNU gdb (GDB) 7.1-ubuntu Copyright (C) 2010 Free Software Foundation, Inc.
