ISVs get sceptical about that, because it's generating code they

Yes, that thinking seems to be a result of C/C++ compiler
shenanigans. People advocating "optimization" based on the
assumption that undefined behaviour does not happen have
suggested that I should keep compiler versions around that
compile my source code as I expect it.

Plain old compiler bugs, introduced while fixing other ones, are quite
enough to make me assume that I'll find problems on each change of
compiler. I have had a manager in a very large software company assure me
that it was impossible for them to add bugs while making fixes. His
technical people corrected him immediately, because I'd just laughed.
