I tried testlwp-static, and it too segfaults, after about 5 context switches.
If the information is useful, it is probably better to use sigaction with the SA_SIGINFO flag set, which is defined by POSIX. I certainly agree that it's better to stick to standards. uc_stack.ss_sp was nonnull, but pointed to 0. Can anyone confirm if head lwp works on any version of NetBSD?
