Nouveau kernel rejected pushbuf on Allegro5-C++ -


i'm in trouble this: i've installed allegro5 on ubuntu, , compiled helloworld project 

#include <allegro5\allegro.h> #include <allegro5\allegro_native_dialog.h> int main(void) {    allegro_display *display=null;    if(!al_init()) {      al_show_native_message_box(null, null, null, "failed initialize allegro!", null, null);      return -1;    }    display=al_create_display(640,    480);    if(!display) {      al_show_native_message_box(null, null, null, "failed initialize display!", null, null);      return -1;    }    al_destroy_display(display);    return 0;  }

with " g++ -wall testprogram.cc pkg-config --libs allegro-5.0 allegro_font-5.0 allegro_ttf-5.0 ". running on terminal, gives me error (or crash?) message:

nac@nac:~$ ./a.out  nouveau: kernel rejected pushbuf: bad file descriptor nouveau: ch0: krec 0 pushes 1 bufs 1 relocs 0 nouveau: ch0: buf 00000000 00000002 00000004 00000004 00000000 nouveau: ch0: psh 00000000 00000004a8 00000004bc nouveau:    0x00107b00 nouveau:    0x00000000 nouveau:    0x20217000 nouveau:    0x00000003 nouveau:    0x1000f010

after tests saw crashes on or after "al_destroy_display(display);", in fact, after error must ctrl+c end program.

how can do??

this question few months old, comes first hit when searching error. had same error running linuxmint 17.2 allegro 5.0.10, , solved updating graphics card (geforce gtx 460) driver. hope helps future users.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
