About SDL2 freeze

[davidsu]

Hello,
I write a game in this board ,
I use SDL2 as my 2D library,
But the game is always random freeze
I use
sudo vcdbg reloc

to dump GPU status

I find "heap corruption detected" in the end of the dump message

How can I find the corrupt position ?
or any other information to help me to solve the problem

the attachment file is the dump message.

sorry about my bad english.

Tks.

[davidsu]

I have some extra information
I use Raspberry Pi 2 with 1G ram,
and resolution 1920x1080 p 60
When it freeze , I use ssh connect to the system and dump some message

It freeze because of "futex_" and in eglSwapBuffers ()

But the same program , when I change config.txt to

hdmi_group=2 (DMT)
hdmi_mode=81 1366x768 60 Hz

It is not freeze ,
I think it is freeze because of egl or driver.

Adn the same program , I disable Loading Message when the png and wav file loading(without use any 2D graphic function) ,
and the resolution is 1920x1080 p 60 ,and It is not freeze too ,

I have a small program will repeat the "freeze problem"

I follow the step of this link to install SDL2 https://solarianprogrammer.com/2015/01/ ... ted-sdl-2/

This is my config.txt , I changed gpu_mem to 640

about my source program ,
It can compile with

"g++ -std=c++0x -Wall -pedantic sdl2_test.cpp -o sdl2_test `sdl2-config --cflags --libs` -lSDL2_image"

1.please tar -zxvf test_sdl_logo.tar.gz to the same folder of the program

2.please put a png file with resolution (1920*1080) file to the same folder and rename to 1.png

then run the program , it will freeze after 30 sec.

if anyone have any idea please help me,thank you everybody.
