This was first reported in #1125 as failed workaround. I'm moving it here since the original bug in #1125 was fixed long ago.
It's in dstress as:

http://dstress.kuehne.cn/run/t/tuple_23_C.d

It's probably related to #1252, #1172, and #1173. It seems that fullstops ('.') are not treated correctly. #1500 may also be related.

void foo(int [] q)
{
  asm{
	mov EAX, q.ptr;
//        mov ECX, q.length; // this doesn't work either
   }
}

There aren't any good workarounds for this. Creating a local variable and using 'naked' are the two best options, but they're both ugly.
