# Regression test for
#
# CLLbs14756
#
# o catch load command does not stop for implicit loads.
#
# CLLbs15382
#
# o sharedlibrary command ignores its argument and ends
# up loading every shared library there is ...
#
# CLLbs15582
#
# o info line non-existent-function dumps core
# o clear non-existent function dumps core
# o xbreak non-existent-function dumps core
#
# CLLbs15725
#
# o gdb prints static and extern variables in shlibs incorrectly.
#
# CLLbs16090
#
# o deferred breakpoints should kick in for shlibs loaded explicitly
# with the sharedlibrary command.
# o GDB confuses export stubs with actual function.
