The title doesn't actually say it all. What happens when you try to run it? It should show some kind of output that might help establish the cause of the problem.
Created attachment 531324 [details] strace for no-lto working lxterminal Oops, my bad! I onlytoke notice of my mistake @emerge -e world@gcc:7.3.0 upgrade. My apologizes...
Created attachment 531326 [details] strace for non working lto lxterminal Didn't investigate yet... Sorry for straight forward push. Wouldn't be surprised culprit to be my too bleeding edge portage default conf.
Without strace, lxterminal command line launch just returns to terminal prompt.
Created attachment 531328 [details] emerge --info for working no-lto lxterminal
Created attachment 531330 [details] emerge --info for non working lto lxterminal
Your emerge --info looks like you haven't only enabled lto, but a whole bunch of obscure compiler flags. None of that is part of any official Gentoo documentation. As far as I'm aware we're also not officially supporting lto-compiled systems. Still: If I compile lxterminal with lto it doesn't crash.
