Hi Alain,

sorry for the late reply. I finally ran the test_acc and then counted 
the different lines in all the fldiff.report files.
( find ./ -name fldiff.report -exec grep "different lines" {}\;| wc -l )

I get between 68 and 75 differences cases depending depending on the 
compiler used.
It seems pretty random to me which cases show up with which compiler and 
how may line in each test differ.

Any hints how may differences are ok (if any)?
best regards,
Samuel
