[LLVMdev] Problems with void*

[Ricardo]

Hello,

I am trying to use the LLVM classes (with Modules in memory) to represent some programs that use
the void* type but I am having some problems handling that type. 
If I use WriteBytecodeToFile, I receive this error:

Assertion `slot != -1 && "Module broken!"`

If I save the module directly with PrintModulePass, it generates the .ll file fine, but if I try
to compile it with llvm-as, as soon as it finds 'void *' it complains that it was expecting an "("
instead of an "*". I suppose that the correct syntax is something like this:  'void (sbyte *)*'

For example, these lines can cause the error:

	%castinst1 = cast typeXYZ* %var to void*		; <void*> [#uses=1]

or

	%astruct = type { %int*, %void*, *astruct }

My question is, how can I generate 'void (sbyte*)*' using the LLVM classes?

Thanks!
