Could you post your exact configure and bootstrap commands, and the bootstrap compiler used? I have been building 4.5 without problems. There is an issue with asms that is unresolved that would affect kernel builds. It may be your bootstrap compiler is broken. Because of this, I wouldn't recommend 4.5 for kernel builds. The annoying thing abour this bug is it doesn't appear with checking enabled and didn't appear until 4.5 was released. It's possible this is a delayed branch issue. > I'll try to provide a testcase but I'm usually unsuccessful while > trying to do so. > > Is there any known issue with -fdelayed-branch ? No. > I know about PR38740 but the fix should be included in 4.5 by now. The fixes for this PR are in 4.3 and later. Dave -- J.
