Describe the bug

When use V compile a translated v code vtcc, it generated wrong c code, which will cause SIGSEGV

Reproduction Steps

a test file, p.v, this case is extracted from vtcc/src/i386-asm.v, function asm_compute_constraints

@[translated]
module main

struct ASMOperand {
        constraint [16]i8
}

fn main() {
        op := &ASMOperand{}
        str := &char(0)
        str = op.constraint

        dump(str)
}

v p.v

Expected Behavior

compile & run OK.

Current Behavior

$ ./p
0x7a8202d88a6c: at ???: RUNTIME ERROR: invalid memory access
/tmp/v_1000/p.01K27AADJKBY9B4WR2J8XB4DP4.tmp.c:2187: by main

Possible Solution

No response

Additional Information/Context

in generated C file:

VV_LOC void main__main(void) {
        main__ASMOperand* op = ((main__ASMOperand*)memdup(&(main__ASMOperand){.constraint = {0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0},}, sizeof(main__ASMOperand)));
        char* str = ((char*)(0));
        memcpy(str, op->constraint, sizeof(Array_fixed_i8_16));
         _v_dump_expr_char__ptr(_S("p.v"), 13, _S("str"), str);
}

It use memcpy instead of a pointer assignment here.

V version
