Product: clang
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: -New Bugs

I'm running Clang from inside a Docker instance running Ubuntu 12.04. Here's a
tiny test case that shows the problem:
root@eacf7e43c75a:~# cat test.c
# include_next <limits.h>
In file included from test.c:1:
/usr/include/limits.h:125:16: fatal error: 'limits.h' file not found
# include_next <limits.h>
^
1 warning and 1 error generated.
root@eacf7e43c75a:~# clang -v
Ubuntu clang version 3.4.1-1~exp1 (branches/release_34) (based on LLVM 3.4.1)

Found candidate GCC installation: /usr/lib/gcc/x86_64-linux-gnu/4.8.1
Selected GCC installation: /usr/bin/../lib/gcc/x86_64-linux-gnu/4.8
However, I have a docker instance I built a couple months ago that's almost
entirely the same, except for what I think is a version bump in clang-3.4:
(the following snippet is from the old image, which handles the test case fine)

Did something change in how clang looks for include files?
