GDB crash
lazarus / 12-Debugger

Hi all,
since I had the 0.9.30.4 version (now I have the latest 1.0) I'm
troubling with the debugger because it crashes every time the
application I want to debug is starting up, for every program I try to
debug (also the empty default application).
The problem has began the day I uninstalled Internet Explorer 8 from
my XP Home, trying to increase pc performances. Supposing the gdb.exe
file needs some specific dll, I re-installed Internet Explorer 8
(included all the patches from Windows Update), but nothing to do:
gdb.exe still raising Access Violation.
Can someone help me?

Nick

Is your CPU 64 or 32 bit?
Is your XP  64 or 32 bit?
And is your Lazarus  64 or 32 bit?

Do you have an antivirus? Which one? Bitdefender and Comodo have in
the past caused trouble.
For Bitdefender try game-mode, comodo see here
http://forum.lazarus.freepascal.org/index.php/topic,7065.0.html

At what time does GDB crash?

Can you start it from console? (startmenu "Run": "cmd.exe", then
change dir to gdb and start it.
Which version does it report (if it starts)

----------------------
If gdb starts in the above:
Lazarus "Project" menu, "project options", tab "linking", try "dwarf2
(with sets)"

Test with an empty new project.

If you use stuff from other packages, they may impose a different
setting. If in works with an empty project, you need to check the
options of any package that you use.

Hi Martin,
CPU, XP and Lazarus are 32 bit.
I have Microsoft Security Essential as antivirus.
GDB crash just when the application is starting. With an empty project
it crash too.

I'll give a try from console asap.

Thank you by now

-----
Current gdb for win 32, include dll. All to go in the same folder.
Ensure you have no other versions of this dll in PATH (e.g. if you
have cygwin or mingw installed):

http://svn.freepascal.org/svn/lazarus/binaries/i386-win32/gdb/bin/

With svn, you can get older versions too (for testing). On mingw is
gdb 7.5. You should not use it. The IDE does not support it yet

-----
If gdb can be started from cmd.exe then please generate a log as
described here

This worked for me. Now the debugger seems ok.

Thanks a lot!
