Hi,
I'm debugging a project with dlopen-ed modules.
In gdb, setting a breakpoint for an as-yet unloaded symbol
makes gdb say:
(gdb) b func_realize
Function "func_realize" not defined.
Make breakpoint pending on future shared library load? (y or [n]) y
Breakpoint 1 (func_realize) pending.
However, the dialog doesn't happen in DDD, making it useless.
I'm using it on debian:
GNU DDD 3.3.11 (i486-pc-linux-gnu)
GNU gdb 6.4.90-debian

That's a problem with ddd, then; ask them. Meanwhile, set break
pending on may help, but who knows how badly that will confuse ddd.

Hi,
That worked ok. Now there's a bug in gdb (when run stand-alone).
The dlopened module is loaded, the breakpoint symbol is resolved,
but the program continues running instead of stopping at the
breakpoint. I'll look into gdb source myself.

Breakpoints in overlays are never made pending. So I think that's
just for shared libraries.

Hi,
In breakpoint.c:break_command_1():line-5214, "pending = 1" is set
when do_captured_parse_breakpoint() does not find a breakpoint.
Does this only ever happen with unloaded shared libraries, or can
other things like overlays cause it too?
