Description

With the help of a custom csmith variant, a program was discovered that causes an unexpected error in the wp plugin. The following program is a reduced minimal example of the failing program discovered by csmith:

    /*@ assigns \nothing; */
    int main()
    {
        int foo = 1;
        1 & (foo & 0x80000000000001LL) << 1;
        return 0;
    }

The crash message is:
