I observed a ssh crash on Win95 too, but only after running ssh-host-config
It went away after deleting the two ssh 22/ lines in c:\windows\services
They don't seem to end with CRNL.

I am not equipped to do serious debugging on my Win95 machine, strace shows
nothing of interest, the stackdump points to cygwin_getservbyname
and dup_ent.
