[gnu-linux] some tests fail when compiled by clang

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Get current svn checkout (r221) and build with clang (3.3)

What is the expected output? What do you see instead?

clang --version
Debian clang version 3.3-3 (branches/release_33) (based on LLVM 3.3)
Target: i386-pc-linux-gnu
Thread model: posix

Could be something specific to Debian GNU/Linux build of clang. Particularly I 
had to configure like that:

./configure CC=clang CXX=clang++ 
CPPFLAGS=-I/usr/include/i386-linux-gnu/c++/4.8/ --enable-minimal

otherwise it failed while trying to use gcc's libstdc++ STL header.

OSX unit tests fail too. Even with 2.0 and even with their gcc. From what I've 
seen it appears that -fno-builtin-malloc and friends have no effect there.

So could be same issue.

Indeed purely caused by clang not paying attention at all to 
-fno-builtin-malloc and optimizing away matching noop-like pairs of malloc/free.

I have a change (not production ready yet) that makes tests pass under clang
