Hi, under load, 'make regress' randomly fails on sparc64 in devel/gmp. It happens on 2 different machines, This happens with 5.0, the 5.1 snapshot and -current.
If the machine running the tests is otherwise idle, it take much longer to fail, or sometimes they can even complete without error. It looks to me like it's a kernel issue with register save/restore. On amd64 I could not cause them to fail... -- Matthieu Herrb
