Re: [hatari-devel] Is it me or the symbols prg option is broken ?

Here is what I get :

> symbols prg
Reading symbols from program 
'/media/Win_NTFS/Jeux/Atari/DiskDur.FAL/Thadoss/RACER/RACER/RACER.PRG' 
symbol table...
0x7 program flags, reloc=0, TOS executable, DRI / GST symbol table.
Trying to load symbol table at offset 0x8cee0...
WARNING: ignoring symbol 'DTA' of B type in slot 1 with invalid offset 
0x183b40 (>= 0xf6cab).
WARNING: ignoring symbol 'MAXY' of D type in slot 6 with invalid offset 
0x104114 (>= 0xe8e4b).
ERROR: too many invalid offsets, skipping rest of symbols!
ERROR: reading symbols from

failed!
'symbols' - load CPU symbols & their addresses
Usage:  symbols <filename|prg|addr|name|free> [<T offset> [<D offset> <B 
offset>]]
    Loads symbol names and their addresses from the given file.
    If there were previously loaded symbols, they're replaced.

    Giving 'prg' instead of a file name, loads DRI/GST symbol table
    from the last program executed through the GEMDOS HD emulation.

    Giving either 'name' or 'addr' instead of a file name, will
    list the currently loaded symbols.  Giving 'free' will remove
    the loaded symbols.

    If one base address/offset is given, its added to all addresses.
    If three offsets are given (and non-zero), they're applied to
    text (T), data (D) and BSS (B) symbols.  Given offsets are used
    only when loading ASCII symbol files.
