DW_AT_upper_bound vs. DW_AT_count is described in DWARF-4: The DW_AT_upper_bound attribute may be replaced by a DW_AT_count attribute, whose value describes the number of elements in the subrange rather than the value of the last element. But your sample DWARF is a case of dynamic bounds which are supported only in experimental branch(es) so far: http://sourceware.org/gdb/wiki/FortranVLA particularly the branch jankratochvil/vla of git://sourceware.org/git/archer.git Jan
