Probably the same issue:
---
char[] f() {
    char[] buff = new char[1];
    buff[0] = 0; // works
    buff.ptr[0] = 0; // works
    *(&buff[0]) = 0; // works
    char* t = &buff[0]; *t = 0;   // error
    foreach(ref el; buff) el = 0; // error
    return buff; 
} 

static assert(f() == "\0");
---
Where `error` means: `Error: cannot cast a read-only string literal to mutable
in CTFE`
