Oh for the days of imperative programming!

y=f(x,...)

x=f(x,...)

was just too easy, I guess.

I can reproduce it on Linux.   It looks like it's related to the power
optimization stuff that was recently checked in.   power(a,b+3) does not
crash but

 >>> a**(b+3)

Program received signal SIGSEGV, Segmentation fault.
