Re: Valgrind is grinding my gears

[David Buchan <pdbuchan yahoo com>]

Sorry for peppering you with emails but I just noticed this statement:

"For newly written code it is recommended
to use the new g_slice API instead of g_malloc() and
friends, as long as objects are not resized during their lifetime and the
object size used at allocation time is still available when freeing" - 
https://developer.gnome.org/glib/unstable/glib-Memory-Slices.html

I do indeed change dimensions of arrays declared within my struct (a lot, in fact). Could this be the cause?

Perhaps relevant, is that I have a large struct which I use to pass stuff amongst functions and callbacks and 
I allocate memory for it in main() thus:

  // Allocate data structure
  data = g_slice_new (MyData);

and then free it at the end:

  g_slice_free (MyData, data);

Maybe Valgrind has trouble with g-sliced memory?

Subject: Valgrind is grinding my gears
 

I have a rather large program I've written in C language which uses GTK+2. My Makefile has:

CCFLAGS = `pkg-config --cflags gtk+-2.0 gmodule-2.0`
LIBS    = `pkg-config --libs   gtk+-2.0 gmodule-2.0`

GCC compiles it without warnings using flags:

-Wall -O -Wuninitialized

My program has several user interface files prepared using
 Glade.

I use the program quite a bit and have no stability issues.

But when I invoke Valgrind at runtime, I get a lot of errors which I can't make any sense of.

I have grabbed a small sample of them here:

http://pdbuchan.com/valgrind.txt

I don't like ignoring errors and warnings, but I don't know what to do with these.

Has anybody else come across these types of Valgrind notifications?


Dave
