Yes. And this one is not safe either:

          F_R_float_F(STACK_2,R_R_durch_R(STACK_0,STACK_1))

even though DEBUG_GCSAFETY will not catch it. (gcc appears to evaluate
function call arguments from right to left. Other compilers could do
it from left to right.)

With some temporary variables and enough pushSTACK, popSTACK you'll
get it GC-safe.

I'll look at it.
