Cannot use valgrind


Hi, recently my program can't be checked by valgrind. I don't know what caused it but it said that there's a segmentation fault. But when I tried running the program, it runs just fine. Is it because my bad design? Because honestly I didn't use design patterns at all. I designed my program as I see fit.

Here's a quick report from valgrind:

I'm no valgrind expert, but from the output it seems to me that valgrind is reporting you several errors like:

Code:
==7763== 1 errors in context 5 of 10:
==7763== Use of uninitialised value of size 4
==7763== at 0x80E8C9F: SDL_GUI::CTTFStringImage::CTTFStringImage(SDL_Surface*, SDL_GUI::CTTFont*, short, short, std::string, unsigned) (TTFStringImage.cpp:54)
==7763== by 0x80EA959: SDL_GUI::CBoxedString::CBoxedString(SDL_Surface*, short, short, short, short, unsigned char, unsigned char, unsigned char, SDL_GUI::CTTFont*, std::string, unsigned) (BoxedString.cpp:99)
==7763== by 0x80E80F4: SDL_GUI::CTextBox::changeValue(std::string) (TextBox.cpp:125)
==7763== by 0x80A9EDE: CGUI_AuditHandler::initCurrentValues() (GUI_AuditHandler.cpp:350)
==7763== by 0x80AFE29: CGUI_AuditHandler::CGUI_AuditHandler(SDL_Surface*) (GUI_AuditHandler.cpp:285)
==7763== by 0x80A1D8E: CTestModeManager::CTestModeManager(CSceneManager*, SDL_Cursor*, SDL_Cursor*, CPrinterHandler*, CSoundManager*, CSettings*) (TestModeManager.cpp:45)
==7763== by 0x806E887: CMattingMain::initialize() (MattingMain.cpp:1257)
==7763== by 0x806F6B0: CMattingMain::CMattingMain(int, int, int, unsigned) (MattingMain.cpp:97)
==7763== by 0x804C688: __static_initialization_and_destruction_0(int, int) (mattinggame.cpp:52)
==7763== by 0x804C6D2: _GLOBAL__I_mThread (mattinggame.cpp:89)
==7763== by 0x80EEF75: (within /home/benang/mattinggame/debug/src/mattinggame)
==7763== by 0x804B864: (within /home/benang/mattinggame/debug/src/mattinggame)
You should check what code do you have at the reported lines.. (for example: mattinggame.cpp:89), and see if you can fix them.
