Yep, now it faults at 8MB instead. So, it must be a runaway recursive function in openssl that causes this.7967 1 openssl CALL __sigprocmask14(3,0x7ffff93c,0) 7967 1 openssl RET __sigprocmask14 07967 1 openssl PSIG SIGSEGV SIG_DFL: code=SEGV_MAPERR, addr=0x7f7ffff8, trap=204)7967 1 openssl NAMI "openssl.core"gdb on this process may tell which function.
I'm not sure how to find that: http://mail-index.netbsd.org/port-vax/2020/02/29/msg003389.html John
