How do i decypher codeblocks.rpt ?

rickg22:
Yiannis was the one that performed the magic. But now I'm stuck with a bug report, and have no idea what to do with the rpt file :-( Does anyone know?

tiwag:
the most interesting thing in the .rpt file is that you find the callstack up to the crash

so walk the callstack down until you find an entry which references to a function which
is coded in the sourcecode of codeBlocks - voila, you know the function which has triggered
the GPF
- the rest you've to manage with a debugger of your trust  :shock:

UPDATE

codeblocks.RPT

...skip the rest...

--- End code ---

1.) Reading from location 00000028.
some pointer contained this value and it is a protected address

2.) callstack
WinMain called ..some others... until
Manager::GetEditorManager()  called 
EditorManager::Get(wxWindow*)  which called 
EditorManager::EditorManager(wxWindow*) and then it crashed in

WindowBase10FindWindow


now look in the source code, the line numbers are given in the call-stack too:

editormanager.cpp

--- Code: ---125:   // *** Load Panel and close button from XRC ***
126:   m_pPanel = wxXmlResource::Get()->LoadPanel(parent,_T("ID_EditorManagerPanel"));
127:   wxBitmapButton* myclosebutton = XRCCTRL(*m_pPanel,_T("ID_EditorManagerCloseButton"),wxBitmapButton);

--- End code ---

so it's most likely that the parameter m_pPanel was invalid at the time of crash,
it was retrieved in line 126 but not checked for validity and used in line 127.


3.) forget the Registers, until you are not programming in assembler and set the registers "by hand"
or you win chess games against Deep-Blue  8) and compile a 1000+ lines sourcecode with your brain not using a compiler,
like the heroes in the 1970ies did, when they developed the first microcontrollers...

rickg22:
ARGH! Well, thanks for the info :)

rickg22:
Um... the codeblocks.rpt I got hasn't gotten any line information... only addresses.

then you have got a rpt file from a stripped version of codeblocks

use the /devel/codeblocks with debug symbols in it to get symbolic information in the rpt
