[Valgrind-users] newbie question for a change ;)

[Mathieu M. <Mat...@cr...>]

Hi all,
	Once again I'll start by saying that I am a newbie and please bear with 
me...blabla

	Ok now I introduced myself ;) I have two questions:

1. What does : "valgrind's libpthread.so: KLUDGED call to: 
pthread_cond_destroy" means ?

I wasn't able to translate KLUDGED ...

2. And what does

" Syscall param writev(vector[...]) contains uninitialised or 
unaddressable byte(s)
at 0x40237951: my_do_syscall3 (vg_libpthread.c:2389)
by 0x40236BA8: vgIntercept_writev (vg_libpthread.c:2055)
by 0x4017BF68: __writev (vg_intercept.c:287)
by 0x43246B45: (within /usr/X11R6/lib/libX11.so.6.2)
Address 0x413C7FD8 is 124 bytes inside a block of size 2048 alloc'd
at 0x40165F4D: calloc (vg_clientfuncs.c:242)
by 0x4321D6FE: XOpenDisplay (in /usr/X11R6/lib/libX11.so.6.2)
by 0x430BEB12: gdk_init_check (in /usr/lib/libgdk-1.2.so.0.9.1)
by 0x42EC3CA1: gtk_init_check (in /usr/lib/libgtk-1.2.so.0.9.1)"

means ? Please note that this message isn't shown if I start my app with 
option '--sync', which mean that X whill be started in synchronize mode 
: XSynchronize(display,True). If this sole message doesn't give any clue 
on what the problem is, could someone told me what to do then (use gtk 
debug lib, X debug lib -if such beast exists-, ...)


I was running valgrind on my linux box with lastest nvidia driver with 
the following command line:

  __GL_FORCE_GENERIC_CPU=1 valgrind -v --leak-check=yes python2.2 wxMyApp.py

thanks,
mathieu
Ps: I am trying to debug an app that works perfectly if using '--sync' 
option but freeze my X session if started without '--sync' option.
