Bug ID: 71623 Summary: Segfault when allocating deferred-length characters to size of a pointer Product: gcc Version: 6.1.1 Status: UNCONFIRMED Severity: normal Priority: P3 Component: fortran Assignee: unassigned at gcc dot gnu.org Reporter: zed.three at gmail dot com Target Milestone: --- Created attachment 38748 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=38748&action=edit MVCE for allocation bug When running the attached MVCE with gfortran 5.4.0 and 6.1.1 (20160615 [gcc-6-branch revision 237474]), there's a segfault on the line: allocate(character(len=size(array_ptr))::string) but not on allocate(character(len=size(array))::string) or allocate(character(len=ptr_size)::string) where array_ptr => array, and ptr_size = size(array_ptr). This works in 4.9.0 and 4.8.3, as well as ifort 14.
