Knowing size of the non-LTO optimised DSO I suppose that sill it maybe some
design issue (higher level) which is causing that inline operations are causing
such gigantic memory usage increase.
And/or maybe it would be good to organise some internal metric with such
operation counter to display at least some warning that some threshold of such
operations has been reached?
Maybe I'm mumbling but I'm trying to find at least sone generic solution to
have some at least linker fart that thing are going in wrong direction because
what is implemented in the code ..
