[Bug 337608] Re: Sun Java Plugin 6 + firefox3.0 - kills X server on Asus EEEPC 1000 + Jaunty Alpha5

[Manoj Iyer]

I wrote some stupid program like below and got similar back trace.. 


main()
{
        char *src = 0;
        char *dst = malloc(1024);

        memcpy(dst, src, 1024);
}


Program received signal SIGSEGV, Segmentation fault.
