Hi Andre, I have posted my results with your patch (and those for pr63851) at
https://gcc.gnu.org/ml/gcc-testresults/2014-12/msg02408.html. I don’t see any problem with unlimited_polymorphic_2.f90. However the character lengths are now wrong (they are 0) with your old patch for pr60289 at https://gcc.gnu.org/ml/fortran/2014-08/msg00022.html. I have also noticed that you don’t comply to the GNU policy about spaces, in particular there should be no space at the end of a line, see the patch for gfortran.dg/unlimited_polymorphic_18.f90. Thanks for working hard on these issues, Dominique > Le 18 déc. 2014 à 19:41, Andre Vehreschild <ve...@gmx.de> a écrit : > > Hi all, > > here is my next try on proposing a patch for the issue in pr60255.
