--- Comment #5 from Manfred Schwarb <manfred99 at gmx dot ch> --- This might have been solved by https://gcc.gnu.org/git/gitweb.cgi?p=gcc.git;h=ac932bfcd21e9523fa2b880ae8138aef79da7f54 , at least I don't see it anymore in today's build. As the crash of class_61.f90 is a bit difficult to reproduce, additional confirmation might be needed.
