Does the bug reproduce if the whole build is rerun from scratch?
I tried six times before reporting: Status: failed halide_19.0.0-6_amd64-20250418T100010.385Z Status: failed halide_19.0.0-6_amd64-20250418T100011.126Z Status: failed halide_19.0.0-6_amd64-20250418T100012.500Z Status: failed halide_19.0.0-6_amd64-20250418T100014.400Z Status: failed halide_19.0.0-6_amd64-20250418T222003.977Z Status: failed halide_19.0.0-6_amd64-20250418T222004.030Z and each time it was made "from scratch". This is not a hand-made build with dpkg-buildpackage, this was a mass rebuild using sbuild.
Looks like it is failing with SIGILL "illegal instruction", what is the CPU there? /proc/cpuinfo?
In this case they are c7i and m7i machines from AWS, so they have a 4th Generation Intel Xeon Scalable processor. The cpuinfo is attached. (If you need a VM to reproduce, please contact me privately) Thanks.
