Comment (by fpretto):

 Recompiling ffmpeg with --disable-sse and --disable-ssse3 fixes the
 problem here.

 For some Euros, I may be interested in bounting the fix of this bug
 (ref[1])

 Oh, I have found another possible bug (assertion failed). Just suppose I
 have the same filter chain: src_buffer and yadif. If I don't insert the
 first frame on src_buffer (so the buffer is empty) and I immediately poll
 the output link of yadif filter, I get:

 Assertion failed!

 Program: C:\Users\ceztko\Staging\target\Debug\Test.exe
 File: libavfilter/vf_yadif.c, Line 277

 Expression: yadif->next

 ...and the executable quits.
