Wrong value printed by info locals for dynamic object. The problem is printing the wrong value for dynamic local variables when using the "info locals" command. Consider the following code: procedure Print (I1 : Positive; I2 : Positive) is type My_String is array (I1 .. I2) of Character; I : My_String := (others => 'A'); S : String (1 .. I2 + 3) := (others => ' '); begin S (I1 .. I2) := String (I); -- BREAK Put_Line (S); end Print; After the debugger stopped at BREAK, we try printing all local variables. Here is what we get: (gdb) info locals i = "["00"]["00"]" s = "["00"]["00"]["00"]["00"]["00"]["00"]["00"]["00"]" Curiously, printing their value using the "print" command works: (gdb) print i $1 = "AA" (gdb) print s $2 = " " We traced the problem to trying to get the contents of a variable (call to value_contents) before "fix'ing" it. For those not familiar with the Ada language support, "fixing" a value consists of swapping the value's dynamic type with a static version that is appropriate for our actual value. As a result, the dynamic type was used to determine the value size, which is zero, and thus the value contents was empty. gdb/ChangeLog: * valprint.c (common_val_print): Fix the value before extracting its contents. * ada-lang.c (ada_to_fixed_value): Make this function extern. * ada-lang.h (ada_to_fixed_value): New function declaration. * ada-valprint.c (ada_value_print): Use ada_to_fixed_value to avoid code duplication and fix a bug in the handling of fixed types contents. gdb/testsuite/ChangeLog: * gdb.ada/dyn_loc: New testcase.
