On x64, 7133857 broke pow(x,y) when x<0 and y is an odd integer. This affects debug builds only. int(y) is moved to an register to be tested for parity but between the load of int(y) and the test for parity some debugging code changes the content of the integer register.
This should affect only the interpreter and c1.
