There are currently two known issues with LTO. The first one is ICE in

unitialized flag_check_pointers when code is compiled by lto1 (do you
know why it may happen BTW?). It also causes ICE beacause instrumented
code is met when not expected. Of course, I'll fix these problems
anyway, but I was going to allow '-fcheck-pointers -flto' only when
checker testsuite has 100% pass rate with lto.
No idea about why LTO would be failing in this way -- my experience with LTO
is virtually nil.
I'm OK with the restriction as a temporary measure. But we really dislike
this kidn of stuff, so I need a commitment from you to dive into these
problems and sort out what's really going on.
I'm not ok with adding such arbitrary restrictions. LTO support should
be trivial.
In that case, Ilya, you've got to resolve the LTO issues before this
can move forward.
