--- Comment #1 from delcypher at gmail dot com ---
I observed this problem myself today.

I'm using

* gcc 4.8.2
* gdb 7.6.1

On Arch Linux (Linux 3.11.6-1 X86_64)

The issue happens with some header files in a project I'm working on but not on
others which is strange.

For example if I do

$ gdb klee
(gdb) start
(gdb) list Expr.h:1
file: "/home/dsl11/dev/klee/klee/bin-dbg-llvm29/../src/include/klee/Expr.h",
line number: 1
file: "/home/dsl11/dev/klee/klee/bin-dbg-llvm29/../src/include/klee/Expr.h",
line number: 1
file: "/home/dsl11/dev/klee/klee/bin-dbg-llvm29/../src/include/klee/Expr.h",
line number: 1

but if I try

(gdb) list Common.h:1
1       //===-- Common.h ------------------------------------------------*- C++
-*-===//
2       //
3       //                     The KLEE Symbolic Virtual Machine
4       //
5       // This file is distributed under the University of Illinois Open

7       //
8      
//===----------------------------------------------------------------------===//
9
10      /*

If I run

(gdb) info sources

I see that both Expr.h and Common.h are in the list of files under "Source
files for which symbols have been read in:"

I cannot reproduce the issue on a simple "Hello World" example. Doing "list
stdio.h:10" succeeds

Any ideas what's going wrong?
