--- Comment #11 from Jerry DeLisle <jvdelisle at gcc dot gnu.org> --- Always helps to double check. The three original test cases do not ICE on trunk and gfc_release_symbol is already NULL guarded internally. I would not chase this further on trunk for the first three cases. Also, we don't care about the listed versions under "known to fail". especially for invalid. Its not worth our time on older gfortran releases. However, it is worth investigating on trunk, especially for learning the internals So which cases actually ICE or segfault on trunk currently? z4.f90 is definitely something different.
