Did you remember to initialise the GValue to {0}? The following
program runs with no warnings for me.
/* Compile with:
gcc -Wall try3.c `pkg-config gobject-2.0 --cflags --libs`
*/
#include <glib-object.h>
static GValue value = { 0 };
static GValue value2 = { 0 };
static void
fred( void )
{
GValue value3 = { 0 };
g_value_init( &value2, G_TYPE_POINTER );
g_value_init( &value3, G_TYPE_POINTER );
}
int
main()
{
g_type_init();
g_value_init( &value, G_TYPE_POINTER );
fred();
return( 0 );
}
