Bug ID: 96839 Summary: gfortran thinks common_bits starts a common block Product: gcc Version: 8.1.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: fortran Assignee: unassigned at gcc dot gnu.org Reporter: w.clodius at icloud dot com Target Milestone: --- Created attachment 49151 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=49151&action=edit A reduced code illustrating the problem. If I have both a member function named bits and an attribute named bits, a combination that is illegal, gfortran 8.1 gets confused and thinks common_bits starts a common block. It took me a while to understand the cause of the error message.
