3392 – a cast of this to void in tango.core.Thread is not allowed

Tango does not compile (just ./build/build.sh ), but stops with an error
{{{
.../Thread.d(659): Error: e2ir: cannot cast from tango.core.Thread.Thread to void*
}}}
this is just a cast of this to void*, even rewriting the lines like this
{{{
 void *arg=cast(void*)cast(Object)this;
 if( pthread_create( &m_addr, &attr, &thread_entryPoint, arg ) != 0 )
}}}
gives an error casting this.
Unfortunately just about any reduced example work...
both 1.048 and 1.049 have this issue, it is a blocker for tango.

Reduced testcase:
class Foo {
	Foo next;
	void start()
	in {
		assert (!next);
	} body { 
		void* p = cast(void*)this;
	}
}

A patch to dmd is in svn now.

thanks!

Works with r208. Thanks!

Fixed DMD1.050 and DMD2.035.
