Dr. Memory fails on DR assertion when an empty or trivial .cpp file is added to the build

Initially filed as https://code.google.com/p/drmemory/issues/detail?id=440 but turns out it's more of a DR problem.

In short, Dr. Memory is a C-only client.
When I try to add a simple C++ file it crashes on start with different symptoms in different configurations.
I'm seeing the following results as of r958 (DrM revision 482 )

DynamoRIO usage error : failure to process imports of client library (dynamorio\core\loader_shared.c, line 120)

the Release build fails to start with a few "WARNING: unable to locate results file since can't open .../resfile" lines printed to stderr.

Patch 2: [attached] // also replaces msvcrt linking with libcmt[d] and adds some simple C++ code to run.
----------------------------------

A larger patch (attached) fails in the Debug build (both DR and DrM are Debug):
...
Usage error: privately-loaded library executed by app:
please report this transparency violation (dynamorio\core\vmareas.c, line 7261)
...
CURIOSITY : name[1] == ':' && (name[2] == '/' || name[2] == '\') && "create file invalid name"
in file dynamorio\core\win32\os.c line 4479
// name = "USER32.DLL" while the drive letter is expected?

If I use Release DR (regardless of the DrM build) it works fine with the second patch.

------------------------------

Are there any known C++ DR clients except for stl_test?
