    But then I'm wondering exactly during which part of read_key_sequence
    is it dangerous to use xmalloc.

Based on that comment, it is dangerous if it would normally happen
again, when read_key_sequence is called again after the error.

Allocating memory in obscure circumstances, after some events have
been read and depending on what events they are, would not pose this
kind of problem, because after the error you could type some other
input and not get the error.
