   That is a very annoying bug in gdb 5.0. When I set a breakpoint in
   the shared library, I have to disable them before restart.

Getting this bug fixed is one of the release criteria for GDB 5.1.
All I have now is a hack that works around the problems, see the GDB
TODO file for more info.

   Also it is very hard to debug ld-linux.so.2:

   # gdb ld-linux.so.2

AFAIK this never worked.  Patches to make it work are certainly
welcome.  Uli mentioned he submitted some patches, but I cannot find
any trace of them.  Perhaps you re-submit them Uli?
