It dumps on Solaris, as well.  This stack trace is from S9/x86.  I don't
know why all the symbols are not being resolved (well, it's not a debug
build, that's why).  I've included the memory mapping as well, which may
help.  The SPARC stack is not the same; I can provide that as well, if
it'd be useful.
