  16 # "catch catch" catchpoint ended up with multiple locations.  This
  17 # testcase exercises that scenario by building the binary with
  18 # -static-libgcc/-static-libstdc++ and a shared library that depends
  19 # on the libstc++.so DSO (which is how GDB was built and revealed the
  20 # bug), and vice versa.
