The test "vmd/test/test_doc_modifiers_return_type.cpp" hangs clang. Reported as https://llvm.org/bugs/show_bug.cgi?id=30546

Evidently clang runs out of memory. Note that with VC++ and gcc the test passes.

I don't know why clang would run out ot memory while VC++ and gcc do not but I have not queried the clang mailing list further about it. An educated guess is that clang calculates some fixed size for the preprocessor and when macro expansions cause that fixed size to overrun you get an out of memory condition. I can hardly believe that the preprocessor is really running out of virtual memory, no matter how complicated the preprocessor code gets in VMD.

When I was discussing the problem with Richard, he opined that that might be a problem, if the preprocessed source exceeded 1 GB in size - which it doesn't. (GCC expands this test to about 700K) So I suspect it is "just a bug" -- Marshall
