I can't recreate this on i686-pc-linux-gnu. What host/target are you
using exactly, is it part of the normal testsuite run or do you
compile it with some special options?
In any case, that line isn't particularly relevant to what the
testcase is testing, so it could be removed completely, or by
specifying kind=8 to len().
