https://gcc.gnu.org/bugzilla/show_bug.cgi?id=92192 --- Comment #1 from Richard Biener --- Building libstdc++ with -flto is not really supported - we apply a fixed symbol export set which isn't tuned for its effects. I remember recent fixes in this area though.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=92163 --- Comment #5 from Jakub Jelinek --- I'm not sure it is what we want though, because it will mean more unnecessary compile time work, -fnon-call-exceptions is not on by default for most languages and even if it is, not all stores can throw.
