[Mono-dev] using coreclr in mono embedding sample project

In order to figure out how to properly use the new coreclr
functionality, verifiers etc, I've taken the
test-metadata.c sample that shows how to simply embed mono, and I'm
adding some coreclr stuff to it.
The sample works and runs fine with core clr disabled.
If I add:
before mono_jit_init(), the mscorlib fails to load. When stepping
trough the program with a debugger,
the point where these two (with coreclr and without) diverge, is that
line 465 of coree.c:
ModuleHandle = LoadLibrary(FileName);
returns a valid handle when coreclr is turned off, and it returns 0 when
coreclr is turned on.
This is on windows, with r135921 runtime+corlib, using msvc2008 built
mono using the stock msvc projectfile.
I'm a bit surprised by this actually, as I wouldn't expect a call into
the win32 api to behave differently based on the
coreclr settings. (the FileName variable is identical in both cases).
Am I doing something wrong?
A verifier related question: in do_mono_image_load(), there are these
mono_verifier_verify_pe_data(). this one requires image->raw_data_len
to be set. (in verify_msdos_header)
mono_verifier_load_pe_data(). this one actually sets
image->raw_data_len. (in do_load_header)
they're executed in the order above, which causes the first one to
always fail for me.
