Indeed it seems to be that the #define signal mysignal changes the
signal() call in mysignal() into mysignal() and thus makes it resursive
which looks like hanging or gives a segfault in gdb (perhaps because of a
smaller stack there). If I add an #undef signal just before the signal
call in bsd-misc.c sshd behaves normally. This would seem to be a bug for
all platforms that doen't have sigaction() and use just signal. Another
workaround might be to always employ the sigaction() emulation of
openbsd-compat for bsd-misc, even if HAVE_SIGACTION is undefined.

Hope that helps.
