The debugger sometimes fails to re-set a breakpoint as follow,
causing it to become disabled:
(gdb) b nested_sub
Breakpoint 1 at 0x401cec: file foo.adb, line 7.
(gdb) b do_nothing
Breakpoint 2 at 0x401cdc: file pck.adb, line 4.
(gdb) run
Starting program: /[...]/foo
Error in re-setting breakpoint 1: Function "nested_sub" not defined.
Breakpoint 2, pck.do_nothing () at pck.adb:4
4 null;
This only happens on machines where the debug-file-directory is
a valid directory name.
The reason behind the error is that the linespec code that re-sets
the breakpoints uses the current_language global when iterating
over a symtab's symbols. However, the that global gets switched from
Ada to C during the startup phase, probably as a side-effect of stopping
in some system code for which debugging info is available. The fix
is to make sure that we use the correct language.

language when iterating over symbols.

The build_address_symbolic funnction filters out data symbols if
their size is set to zero. But the problem is that the COFF symbol
table (for instance) does not provide any size information, leaving
the size to its default value of zero, thus always triggering
the filter.
This shows up when trying to print the address of a global variable
when debugging a Windows executable, for instance.

Assuming the following declarations:
type Discriminants_Record (A : Integer; B : Boolean) is record
C : Float;
end record;
Z : Discriminants_Record := (A => 1, B => False, C => 2.0);
If variable Z is not used, and the compiler optimizes it out,
GDB would crash as follow:
(gdb) print Z
/[...]/gdb/valops.c:1121: internal-error: Unexpected lazy value type.
This is because the ada-lang module forgot to set the optimized_out
flag in the value returned by ada_evaluate_subexp during the value's
"fixing" process. Later on, when trying to print the resulting value,
GDB finds that the value is still lazily allocated, and thus tries to
fetch it. But this is not allowed for not_lval values, hence the internal
error.
