Keith Randall 1b6807bb06 cgo: adjust return value location to account for stack copies. ... During a cgo call, the stack can be copied. This copy invalidates the pointer that cgo has into the return value area. To fix this problem, pass the address of the location containing the stack top value (which is in the G struct). For cgo functions which return values, read the stktop before and after the cgo call to compute the adjustment necessary to write the return value.
