The switch from `-flto=auto` to > `-flto=$(JOBS)` doesn't seem to have helped in that respect. Turns out I didn't wait long enough. It does terminate after about 40 minutes, though not successfully. Instead the build crashes with a failed assert: # Internal Error (../../src/hotspot/share/runtime/handles.inline.hpp:76), pid=4017588, tid=4017620 # assert(_thread->is_in_live_stack((address)this)) failed: not on stack? I've not tried to debug this. Maybe it's a consequence of one of those problems of bypassing an intentional implicit noinline in our code (by ensuring a function definition is in a different TU from all callers), with LTO breaking that. Or maybe LTO is breaking us in some other way (such as taking advantage of no-UB constraints that aren't found by normal compilation). ------------- PR Comment: https://git.openjdk.org/jdk/pull/22464#issuecomment-2582389338
