It was intended to become a reproducer for the optimization bug in https://gcc.gnu.org/bugzilla/show_bug.cgi?id=110311 but this is a separate issue. I will work around this one in the reproducer for 110311. In the most recent master branch, 14.0.0, it leads to internal compiler error: Segmentation fault 0xd6eabf crash_signal ../../gcc/toplev.cc:314 0x7fe2411f151f ??? ./signal/../sysdeps/unix/sysv/linux/x86_64/libc_sigaction.c:0 0x844f2b structure_alloc_comps ../../gcc/fortran/trans-array.cc:9228 0x8459bf structure_alloc_comps ../../gcc/fortran/trans-array.cc:9167 0x847e8c gfc_deallocate_alloc_comp(gfc_symbol*, tree_node*, int, int) ../../gcc/fortran/trans-array.cc:10265 0x86980a gfc_conv_procedure_call(gfc_se*, gfc_symbol*, gfc_actual_arglist*, gfc_expr*, vec<tree_node*, va_gc, vl_embed>*) ../../gcc/fortran/trans-expr.cc:6940 0x8b1952 gfc_trans_call(gfc_code*, bool, tree_node*, tree_node*, bool) ../../gcc/fortran/trans-stmt.cc:424 0x82f93b trans_code ../../gcc/fortran/trans.cc:2297 0x8b5c30 gfc_trans_block_construct(gfc_code*) ../../gcc/fortran/trans-stmt.cc:2351 0x82f887 trans_code ../../gcc/fortran/trans.cc:2325 0x85da69 gfc_generate_function_code(gfc_namespace*) ../../gcc/fortran/trans-decl.cc:7717 0x833ec1 gfc_generate_module_code(gfc_namespace*) ../../gcc/fortran/trans.cc:2651 0x7d42f5 translate_all_program_units ../../gcc/fortran/parse.cc:6914 0x7d42f5 gfc_parse_file() ../../gcc/fortran/parse.cc:7233 0x82c6ef gfc_be_parse_file ../../gcc/fortran/f95-lang.cc:229 Please submit a full bug report, with preprocessed source.
