Jim,
Thanks for pointing this out. Yes, Load Symbols Lazily" is off. When
attaching to the process, gdb does seem to load symbols. But trying
to set any additional breakpoint tells me that no symbol table is
loaded… Weird. Any other idea?
Not without more information. Can you turn on the Xcode/gdb log (in
Xcode 3.0 there's a preference in the Debugging Pref Pane to do this)
and file a bug with the log & some description of what you did? That
might give us a little more to go on.

I'm trying to debug a JNI plugin here. I use Eclipse for Java Rich
Client Platform development and Xcode for the C/C++ JNI stuff. I
can do the following: start debugging in Java, break on the first
line of main(), go to a terminal, and type
$ gdb
...
(gdb) attach <javaprocesspid>
Then I can set breakpoints on the command line successfully, but I
don't want to go through this terminal debugger. Therefore I set
up a dummy executable in my Xcode project, uncheck "Start
executable after starting debugger", start a debug session, and
try to attach to the paused Java code. I can successfully attach,
but if I then list my breakpoints with
(gdb) info break
I can see that they are all pending. I also cannot add any other,
including the exact ones that I could add on the terminal gdb I
used before.
How can I fix this? What does Xcode do to gdb such that it cannot
find my breakpoints?
TIA,
J.P.
