OK, but to get the helloworld sample working using the
hello.exe image does ilrun have to spawn cscc-cs?

I've looked at the CVM dump output on OSX and it contains over
3,100 lines compared to the one that crashes on my platform
which contains just 511 lines.

I can see that the crash occurs on the very first call to COP_L2I:

and it happens when '&(stacktop[-CVM_WORDS_PER_LONG])' is
de-referenced that I get an error accessing out of range memory.

The method->member.name at this point is 'InternalCodePage'.

At this point the platform contains just the hello.exe image and
mscorlib.dll. Are there other supporting components required at
this point?
