I think the change looks fine to fix the bots, but I don't see anything wrong with the existing code myself. 
At a glance I suspect we're hitting some ordering issue between overloads 1-4 and A-C as listed here: https://en.cppreference.com/w/cpp/numeric/complex/pow 
I'm not even clear whether 1-4 should be considered more specialised than A-C here, but I feel that they should be!

I agree you should go ahead and merge this to make the bots green again while we find out more though.
