This and the other new test fail for me on both x86-64 systems I tried - the
f3 line isn't present in gprof output. I fear I don't have the time to
investigate from grounds up. IOW either I need pointers that make
investigation reasonably easy, or I'll propose to disable the tests again
until this is sorted. The one thing I did check is that the object file has
all the supposed calls to mcount(). If it matters, one system is using gcc5,
the other gcc7.
