It's a bit suspicious why not many others are seeing this issue.
Suspecting the GCC version/build flags has something to do here.

As mentioned by Ken - ideally we won't be pulling C++ into libEGL. Can
you give try converting string_to_uint_map to C?
Alternatively use the dummy.cpp suggestion from Matt. We already have
some examples in the codebase.
