For the NIfTI regression tests, we run a binary for each ADD_TEST -- i.e. we build, e.g. a program called nifti1_test. Then each test is of the form
ADD_TEST(exampletest $(NIFTIUTILS_BINARY_DIR}/nifti1_test --testname exampletest)
There are about 10 different executions of nifti1_test every time you do a 'make test'. When you have coverage turned on, doesn't each execution overwrite the previous coverage data file?
If so, we're only getting coverage results for the last execution of nifti1_test, or am I missing something?
