Does the test reliably fail with the new compiler? It sounds like it might be unrelated, as there have been a number of changes around FMV lately. The test looks like it fork()'s, so maybe something was going wrong with it? If it is a real failure cause by this patch then you might need to debug a bit to see what might be going wrong.
