"OleRPCNotify" is not a program, it is an API (Application
Programming Interface). It's part of the "OLE" subsystem, probably
part of OLE 2.0 (which for a while was called ActiveX and is now
called COM, for those keeping score...).
OLE (or whatever) allows one program to look like a component in
another. [It does a bunch of other stuff too.] Programs that can
use other applications ("containers") need to initialize OLE support,
and need to remove it when they exit. Programs that can be
"embedded" using OLE ("controls") need to check for activation via
OLE when started, and need to tell OLE to go back to the container on
exit.
I suspect that this newer version of Eudora is an OLE container
(making it easy to look at, say, Word or Excel files sent as
attachments, from apparently inside Eudora), and that it may have got
a step or two out of order in the shutdown code, passing a reference
(handle or pointer) that has already been freed.
You'd think that Qualcomm would catch this, but you're only seeing
it through CrashGuard which they may never have tried it with. Odds
are good that the API call, given an invalid reference, fails quietly
(perhasp with a memory/resource leak...), so even if it returned an
internal error code, they may not have considered it serious enough
to stop production.
