six files in one. file name preceeds content. Not sure how to attach more
than one file.
Program compiles with[out] optimization -O1 and executes. Compiled with
profiling without optimization, executes. Compiled with profiling and
optimization, seg faults with call to mcount() (from /lib64/libc.so.6 as
determined from dynamic library build).
obtained clang-3.7.0 from: <a href="http://llvm.org/releases/download.html">http://llvm.org/releases/download.html</a>
clang/llvm built from scratch on rhel6.5 using:
glibc.i686 2.12-1.166.el6_7.3 @rhel-x86_64-server-6
glibc.x86_64 2.12-1.166.el6_7.3 @rhel-x86_64-server-6
devtoolset-3.x86_64 3.1-12.el6 @rhel-x86_64-server-6-rhscl-1
gcc (GCC) 4.9.2 20150212 (Red Hat 4.9.2-6)
Clang build consisted of llvm, cfe, compiler-rt tools. I'll continue to build
and incorporate the additional llvm tools and libraries. Poked a lot at this
and will appreciate all help that can be rendered.</pre>
