So does FFmpeg run out-of-memory or are you just reporting 
that it allocates a lot of memory?

Very generally: Are you reporting a leak (valgrind output 
needed) or oom?

And are you reporting that what you tried worked fine with 
older versions of FFmpeg but fails with a newer one?

In a case like yours, testing current FFmpeg is absolutely 
necessary.

Note that this option has no effect (does not exist) 
since about a decade.

I wonder if the filter system tries to read input as fast as 
possible, no matter how slow or fast the later filters in 
the chain work...
