Interesting. It would appear that you're linking two instances of libaqbanking.dylib (and perhaps libgwenhywfar.dylib too). "info shared" will list all of the dylibs in the image; you can look through the result and see if there are in fact multiple instances and if they point to different files or are merely linked through different paths. Anyway, for some reason, the breakpoint on GWEN_Inherit_FindData isn't attaching to the right place: The function that should be called is (as I wrote earlier) in inherit.c. Since the breakpoint isn't working, try stepping (use "s" instead of "n") into the macro. Make sure first of all that the abgui.c breakpoint is really stopping at the GWEN_INHERIT_GETDATA line, then step into it . Since the macro is only a single line you should be in GWEN_Inherit_FindData with a single "s". Once there, you can go back to "n" to watch the loop. Oh, are you turning off optimization in CFLAGS (-O0)? The optimizer will often screw up symbols and make tracing through code difficult.
