Given the following example:
----------------------------------------
program project1;
{$mode objfpc}{$H+}
procedure doit (var s : ansistring);
begin
s := s + ' ' + s;
end;
var
s : ansistring;
begin
s := 'test';
doit(s);
end.
----------------------------------------
When I compile for x86_64 with "fpc -Px86_64 -g -gl -gw project1.lpr",
and set a breakpoint in "doit" in GDB, I see the following:
(gdb) whatis S
type = &ANSISTRING
(gdb) print S
$12 = (&ANSISTRING) @0x627130
(gdb) whatis S^
type = ANSISTRING
(gdb) print S^
$13 = 116 't'
(gdb) x/s S
0x74: <Address 0x74 out of bounds>
(gdb) x/s S^
0x74: <Address 0x74 out of bounds>
When I compile with "fpc -Px86_64 -g -gl project1.lpr", I get the same
result. When I compile for i386 with "fpc -Pi386 -g -gl -gw
project1.lpr", I have the same issue. However, when I compile for i386
with "fpc -Pi386 -g -gl project1.lpr", I get:
(gdb) whatis S
type = ANSISTRING
(gdb) print S
$1 = (ANSISTRING) 0x8064074 "test"
(gdb) x/s S
0x8064074 <_$PROJECT1$_Ld3>: "test"
How can I print the value of a var ansistring parameter in gdb with
dwarf debugging information compiled in?
I am compiling with FPC 2.4.0 (built from svn from the 2.4.0 release
tag) on Ubuntu 9.10 x86_64.
Thanks,
