Bug ID: 110691 Summary: Segmentation fault on valid F2018 code Product: gcc Version: 14.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: fortran Assignee: unassigned at gcc dot gnu.org Reporter: juergen.reuter at desy dot de Target Milestone: --- Created attachment 55557 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=55557&action=edit Reproducer The attached code (which I believe to be valid F2018) leads to a segmentation violation with gfortran at least since version 11. (it also seg faults, probably with a different root case) in Intel oneAPI 21.9 (2023 v1), but works with nagfor. This is the backtrace of the segfault: Program received signal SIGSEGV, Segmentation fault. 0x000055555555d841 in __qn_containers_MOD_qn_array_copy () (gdb) bt #0 0x000055555555d841 in __qn_containers_MOD_qn_array_copy () #1 0x000055555555e3f3 in __qn_containers_MOD_qn_container_grow () #2 0x000055555555d2a5 in __qn_containers_MOD_qn_array_append () #3 0x0000555555560742 in __qn_containers_uti_MOD_qn_containers_2 () #4 0x0000555555563fb0 in __qn_containers_ut_MOD_qn_containers_test () #5 0x0000555555563fc6 in MAIN__ () The reproducer of ca 1200 lines is attached.
