My initial problem was with -r329465, which is after -r329461 reverted -r329488 . Trond reported in one note that he had problems with -r329464 , also after -r329488 was reverted. Trond has also reported -r329449 failed. I did manage to revert to -r329447 earlier and so far the results suggests that it works. =46rom this I get that -r329449 is the the one that is common to all the so--far failing combinations. -r329448 is not common to all of them. =3D=3D=3D Mark Millard marklmi at yahoo.com ( markmi at dsl-only.net is going away in 2018-Feb, late)
