I reproduced the error, it happens the same to me, but it actually
generates the keys, but you get that error. I did a trace. I'm rather
new in OpenBSD, looks like it could be related with mprotect(2), but not
sure. Maybe you should submit the bug:
2620 ssh-keygen CALL mprotect(0x5913d95f000,0x2000,0x3<PROT_READ|PROT_WRITE>)
2620 ssh-keygen RET mprotect 0
2620 ssh-keygen CALL mprotect(0x5913d95f000,0x2000,0x1<PROT_READ>)
2620 ssh-keygen RET mprotect 0
2620 ssh-keygen CALL sigprocmask(SIG_SETMASK,0<>)
2620 ssh-keygen RET sigprocmask ~0x10100<SIGKILL|SIGSTOP>
2620 ssh-keygen CALL fstat(3,0x7f7ffffd2360)
