Jim, thanks for your insight. Some more questions. I don't quite
understand why /usr/lib/dld.sl gets involved while ldd process shows
only /usr/lib/libdld.2 and some others without /usr/lib/dld.sl. tusc
does show that /usr/lib/dld.sl is opened. Shouldn't ldd show it and
why not?

Back to my original core dump. What are the prototypes and
functionalities of _dld_main() and finish_dld_main()? I'm trying to
get more info on what happened and why _dld_main() failed. Thanks. -
