The last line adds a second series of data to the Results table now labelled as ROIs but still the results are for area and not feret's data. Strangely enough the first few times the values for area were the correct values but after I moved some code around they now show zeros.

Dear Kees,
This bug is fixed in the latest ImageJ daily build (1.51r18). Or work around it by adding
run("Clear Results”);
after running the particle analyzer, as in this version of your test macro:
run("Blobs (25K)");
setAutoThreshold("Default");
setOption("BlackBackground", false);
run("Convert to Mask");
run("Set Measurements...", "display redirect=None decimal=0");
run("Analyze Particles...", "size=1-Infinity summarize add");
run("Clear Results");
run("Set Measurements...", "feret's display redirect=None decimal=3");
roiManager("Measure”);
