...ed with -O, instead of -O3 -fomit-frame-pointer. openssh is being compiled with -O2 -fstrict-aliasing. In the case I've investigated with gdb, ssh-keygen dies the first time it gets to RC4_set_key (openssl), called from arc4random_stir. It dies trying to write into the memory of "static RC4_KEY rc4;" (openbsd-compat/bsd-arc4random.c). If, just for sport, I *initialize* rc4 [with zeros] (i.e. it ends up in the data section, not bss), then we sail past this problem [but it dies a bit later in some rsa code]. Do these further details spark any thoughts? (I suspect something in the com...

Hello again, I was testing today's SNAP (openssh-SNAP-20000830.tar.gz) in my Solaris 2.6-8 environment, when I found some problems with the ssh2 support. While connecting, it seeds the RNG something like 32 times! And then once connected, it seeds again 2 or 3 times with *every* keystroke! This makes for some slow going. This happens on all of the Solaris boxes I tried. Binary was
