Comment (by jberryman):

 Sorry I think my description above was a little unclear; it ''does'' I
 think look like the generated code is just setting up the registers and
 doing a jump, which is what I was expecting/hoping (although maybe a GC is
 being triggered and I don't know what that looks like). It was suggested
 that this might be a "display bug" that might cause issues down the line.
