Ok, did that.

I'm getting SIGILL when started w/o debugger, and SIGSEGV when started 
with debugger.

I did some more research, and if I read the code correctly, 
'NS_InvokeByIndex' is supposed to
copy the function parameters (described in 'params' and 'paramCount') to 
the stack ('invoke_copy_to_stack'),
load the parameters from the stack to the registers and chain to the 
desired function.

Now in the failing case, 'paramCount' is one, athough the requested 
function 'nsXPCComponents::SetReturnCode'
expects two parameters (or three with 'this', I don't know if it's 
counted in 'paramCount').

regards,
chris
