problems with gdb

[Matej Kosik]

I am using Redhat 7.0, gcc-3.0, patched gdb-5.0 and just updated and
compiled gnustep-cvs

my attempt

        [root@localhost objc]# cd shared_debug_obj/ix86/linux-gnu/gnu-gnu-gnu/
        
        # the program was compiled without problems and works as I expected
        [root@localhost gnu-gnu-gnu]# ./LogTest 
        Jul 21 07:54:22 LogTest[11266] No local time zone specified.
        Jul 21 07:54:23 LogTest[11266] Using time zone with absolute offset 0.
        Jul 21 07:54:22 LogTest[11266] Executing

        # but my `gdb' session looks like this
        [root@localhost gnu-gnu-gnu]# gdb LogTest

        (gdb) b main
        Breakpoint 1 at 0x8051d94
# THE FIRST PROBLEM ... I can't see the source code [when I was using
stable versions of gnustep packages
# from `ftp.gnustep.org' I did not have this problem]
        (gdb) l

# from `ftp.gnustep.org' I did not have this problem]
        (gdb) n
        Single stepping until exit from function main, 
        which has no line number information.

        Program exited normally.
# THE THIRD PROBLEM I can't run my program in the debugger more than
once [It occured also when I was using 
# gnustep-base from `ftp.gnustep.org']
        (gdb) r
        Starting program:
/root/work/objc/shared_debug_obj/ix86/linux-gnu/gnu-gnu-gnu/LogTest 
        warning: Cannot insert breakpoint -2:
        Cannot access memory at address 0x40280d38
        (gdb) r
        The program being debugged has been started already.
        Start it from the beginning? (y or n) y

        Starting program:
/root/work/objc/shared_debug_obj/ix86/linux-gnu/gnu-gnu-gnu/LogTest 
        warning: Cannot insert breakpoint -2:
        Cannot access memory at address 0x40280d38
        (gdb) q
        The program is running.  Exit anyway? (y or n) y
        [root@localhost gnu-gnu-gnu]# 

yesterday when I noticed this problem I guested my `gdb' went somehow
wrong, so I successfully recompiled it 
with ObjectiveC support [`gdb.compilation' file contains the command by
which I made it]

this did not helped me, so I have recompiled my testing program again
[`LogTest.compile contains the commands
which I have performed and messages which I have obtained]

this did not helped me, so I have updated my gnustep-cvs and
successfully recompiled [`gs.compilation']

? PROBLEM 1 and 2 surprised me ... what am doing wrong?
? does anybody have PROBLEM 3
