Consider the following code: type Index is (Index1, Index2); Size : constant Integer := 10; for Index use (Index1 => 1, Index2 => Size); type Array_Index_Enum is array (Index) of Integer; my_table : Array_Index_Enum :=(others => 42); When compiling the code above with a compiler where the GNAT encodings are turned off (which can be temporarily emulated by using the compiler switch -fgnat-encodings=minimal), printing this table in gdb leads to: (gdb) p my_table $1 = (42, 42, 4203344, 10, -8320, 32767, 4203465, 0, 0, 0) The displayed content is wrong since the handling part believes that the length of the array is max index value (10) minus the first index value (1) i+ 1 = 10 which is wrong since index are not contiguous in this case. The right behavior is to detect that the array is using enumeration index hence parse the enumeration values in order to get the number of indexes in this array (2 indexes here). This patch fixes this issue and changes the output as follow: (gdb) p my_table $1 = (42, 42) gdb/ChangeLog: * ada-valprint.c (val_print_packed_array_elements): Use proper number of elements when printing an array indexed by an enumeration type. gdb/testsuite/ChangeLog (Joel Brobecker <brobecker@adacore.com>): * gdb.ada/arr_enum_idx_w_gap.exp * gdb.ada/arr_enum_idx_w_gap/foo_q418_043.adb Tested on x86_64-linux.
