Changed paths: M op.c M t/op/cmpchain.t Log Message: ----------- skip trying to constant fold an incomplete op tree This code would try to constant fold an op tree like relop +- null +- constant which would underflow the stack, potentially crashing perl. This is intended as a quick fix rather than as a complete solution. Fixes #18380
