Aha, that would explain that, indeed as it. Checking on two of the buildds: root@tirpitz:~> cat /proc/sys/kernel/randomize_va_space 2 root@tirpitz:~> yamashiro:~# cat /proc/sys/kernel/randomize_va_space 2 yamashiro:~# > It looks that the log for 4.8.4-2 includes > gcc/d/ctfeexpr.dmd.o differs > line just after its 'Bootstrap comparison failure!' line. It looks that > that is the cause of failure and is a differnt issue. Ah, thanks for spotting that. Now, should we move this into a new bug report then? > For the original PR, I've apply the fix on 5/6 in behalf of Oleg after > the regtest on trunk which has become possible because 66181 is fixed. Great. Can't wait for the new gcc-5 package to arrive in Debian. Will report back as soon as I know more. Adrian
