Possible Bug SFML 2.0 RC [Solved]
« on: July 09, 2012, 12:19:19 pm »
I'm not sure where to report this.  Sometimes exiting will lead to a seg fault.  Using gdb, I am getting the following backtrace:

Program received signal SIGSEGV, Segmentation fault.
0x0000003a3ea7925c in _int_free (av=0x3a3ed951e0, p=0x31fa7a0, have_lock=0) at malloc.c:4973

Is this just an issue with my video driver?

Can you show a complete and minimal code that reproduces this problem?

It was my fault, I believe.

I am trying to use VBOs in my application and something about window.close, if called before I release the vbo memory seemed to be giving me issues.

Thanks!
