In parse_line(), spaces increment the arg count and it is incremented again on '#' or end of line, resulting in an extra empty arg at the end of arg's list. The visible effect is that the reported arg count is in excess of 1. It doesn't seem to affect regular function but specialized ones like anonymisation depends on this count. This is the second attempt for this problem, here the explanation : When called for the first line, no <out> was allocated yet so it's NULL, letting the caller realloc a larger line if needed. However the words are parsed and their respective args[arg] are filled with out+position, which means that while the first arg is NULL, the other ones are no and fail the test that was meant to avoid dereferencing a NULL. Let's simply check <out> instead of <args> since the latter is always derived from the former and cannot be NULL without the former also being. This may need to be backported to stable versions.
