This might be the same as problem 1967.
>How-To-Repeat:
dbgtest2.pas:
------------------------------
procedure MainProc;
var
x : integer;
begin
x := 5;
writeln('x=',x);
end;
begin
MainProc;
end.
------------------------
# fpc dbgtest2.pas
# gdb dbgtest2
...
(gdb) break MAINPROC
Breakpoint 1 at 0x4001a4: file dbgtest2.pas, line 5.
(gdb) run
Starting program: /work/dbgtest64/dbgtest2
Breakpoint 1, MAINPROC () at dbgtest2.pas:5
5 x := 5;
(gdb) step
6 writeln('x=',x);
(gdb) print X
Cannot access memory at address 0x80003877108c
