Additional: If I compile the entire code “O0” then all behaves as expected. The issue seems to be when compiing (say) O2 and a function has a local optimisation set lower (O0) .. perhaps this is a target problem .. although looking at say tree-ssa-ccp.cc I do not see any gating on the optimisation level - which I guess suggests once it’s selected in the stack .. it’s going to run… any insights would be welcome.
