Still the armhf architecture build fails but due to Bens package change the testsuite.log is visible. All four
failing tests fail due to a segmentation fault. The failing tests are:
297: split-file.at:61 SPLIT FILE - vs procedures
485: means.at:247 MEANS harmonic and geometric means
487: means.at:349 MEANS missing=table
488: means.at:459 MEANS user missing values
I did a build on the Debian machine "harris". All of these tests fail
with the same backtrace:

I'll take a further look.
Looking further, this looks like a compiler bug to me. In the
update_n() function in src/language/stats/means.c, sometimes the
parameter 'c' changes from its original value to NULL between loop
iterations. When I turn off compiler optimization, all of these tests
pass.
I don't see much value in spending much time on this. I think that I
will upload a package that turns off compiler optimization on armhf.
