Is it reproduceable? "The bug is not reproducible, so it is likely a hardware or OS problem." suggests that it is not, the driver in case of ICEs retries to compile the same source 3 times and if they don't fail the same all the time, which is this case, it is likely HW bug. Of course there are chances that this 3 times rebuild doesn't work reliably after being ported to 4.7 (in 4.6 I'm pretty sure it is), but there haven't been any significant changes to it, or there might be a bug triggered by ASLR. So, even if you can't reproduce it, please try to stop the build after this spot and try to run the simplify-rtx.c -fprofile-use compilation many times in a loop to see if it triggers. Unfortunately this is FDO, so it might depend on the simplify-rtx.gcda file changing concurrently from other compilations. And if you can reproduce it, I'm interested in both the preprocessed source (simplify-rtx.i) and simplify-rtx.gcda as well. Created attachment 551177 [details]

well and truly fixed. Jakub thank you for your assistance |
