This sounds like you are including math.h and then later on cmath. I don't
know if this is a valid thing to do.

It's perfectly valid to do that.
Without a testcase we can't do anything, please read http://gcc.gnu.org/bugs/

Hi,
Added the *.ii file and g++ -v output. Since one file was large, links are

The g++ output I found at your pastebin link, however, I do not see the .ii
file.

Are you sure?
I get the same result with GCC 4.7.4, but only with -std=c++11

--- Comment #9 from Dilawar Singh <dilawar.s.rajput at gmail dot com> ---
The snippet I sent you (in url filed) is a part of large project which compiles
fine on Ubuntu-server (gcc4.7.x, I am not sure about x).
I will confirm it later once I login onto server again. Once I change `isnan`
to `std::isnan` in my project, it compiles fine with my g++-4.8.1.

Yes. It is very similar to this. Fine with me if it is marked dup.
I was mistaken about gcc version on server. It is default gcc comes with
Ubuntu-Precice (gcc-4.6.3). Also -std=c++0x flag is not set with gcc-4.6.3. So
in nutshell, compiles with gcc4.6.3 without -std=c++0x, but fails with
gcc-4.8.0 with -std=c++0x.
I mentioned -std=c++11 wrongly in first report.

Same problem exists in 4.9.2.
In my code combining <cmath> with <vector> (later includes os_defines.h then
features.h and mathcalls.h) produce same effect.
