Berrang=C3=A9 The TSAN job started failing when gitlab rolled out their latest release. The root cause is a change in the Google COS version used on shared runners. This brings a kernel running with vm.mmap_rnd_bits =3D 31 which is incompatible with TSAN in LLVM < 18, which only supports upto '28'. LLVM 18 can support upto '30', and failing that will re-exec itself to turn off VA randomization. Our LLVM is too old for now, but we can run with 'setarch -R make ..' to turn off VA randomization ourselves. Signed-off-by: Daniel P.
