It shouldn't be done. Whether it *can* be done is an implementation
detail. In many languages you can create interesting effects by
writing to an array with an out-of-bounds index. That doesn't mean
it *should* be done, and it's also not something usually advertised
in language tutorials.

Then mdoc is buggy and should be fixed. ("Not work reliable" is a
different expression for "it's badly programmed".)
