this tells you that a test failed - but not why - perhaps you will find 
messages about assertion failures further up in the output?  those would 
be interesting...

perhaps it's a good idea to first do a build of the upstream master, 
without your changes?  then you'll know if your changes introduced the 
test failures or not.

to find out why the tests fail, use e.g. the gdb command that is 
printed, together with CPPUNIT_TEST_NAME to limit it to the failing test(s).
