test/invalid-matrix deliberately feeds garbage into the API to test our error detection. This causes FPE to be raised during the course of the test - so they are deliberately disable for the duration. However, the exceptions were not being cleared and so the FPE could be triggered on the next floating point operation. This was being masked during make check, by the fact that each test is run in its own forked process and was only observed when multiple tests were run in foreground mode.
