C++ glibc detected double free or corruption(!prev) using shared library
Currently I test a shared library vendor provided in linux , the following is the simple source :

Code:
#include <iostream>
using namespace std;
 
extern int test1();
extern int test2();
 
int main()
{
    cout << "hello world" << endl ;
    return 0 ;
    cout << "Test 1" << endl;
    test1();
 
    cout << "Test 2" << endl;
    test2();
 
    return 0;
}

I have compile and link like :
Code:
g++ -g -Wall -fPIC -D_DEBUG -o test -I./include32 src/xxx.cpp src/yyy.cpp src/test.cpp -L./lib32 -lshare1 -lshared2

I have the following output while run :

Code:
hello world
***glibc detected *** ./test: double free or corrution (!prev) 0x00000000077ec30 ***

What I don't get is , since I only do print "hello world" and then return 0 ,
that mean I don't call any function in libshared1.so and libshared2.so ,
why error like glibc detected happen ? does it mean that shared library
has problem to be loaded to memory ? since the main function never call
test1() , test2() which really call functions in libshared1.so and
libshared2.so !!

And suggestions , comments are most appreciated !!

gui_ctext_proc

gui_shadow_box_proc(3alleg4)					  Allegro manual				      gui_shadow_box_proc(3alleg4)

NAME

       gui_shadow_box_proc,  gui_ctext_proc,  gui_button_proc,	gui_edit_proc, gui_list_proc, gui_text_list_proc - Hooks to customise the look and
       feel of Allegro dialogs.

SYNOPSIS

       #include <allegro.h>

       extern int (*gui_shadow_box_proc)(int msg, struct DIALOG *d, int c);

       extern int (*gui_ctext_proc)(int msg, struct DIALOG *d, int c);

       extern int (*gui_button_proc)(int msg, struct DIALOG *d, int c);

       extern int (*gui_edit_proc)(int msg, struct DIALOG *d, int c);

       extern int (*gui_list_proc)(int msg, struct DIALOG *d, int c);

       extern int (*gui_text_list_proc)(int msg, struct DIALOG *d, int c);

DESCRIPTION

       If set, these functions will be used by the standard Allegro dialogs.   This  allows  you  to  customise  the  look  and  feel,	much  like
       gui_fg_color and gui_bg_color, but much more flexibly.
