Comment:

 Regression since 044c09c0a0b5e2d91d75619c1327e232a4914030. Before that
 commit, encoding simply failed with "picture could not fit ratecontrol
 constraints, increase qmax". Since that commit, one receives three
 "Internal error, put_bits buffer too small" error messages (these lead to
 asserts in case --assert-level is set to two) and runs twice into the
 assert "s->buf_ptr < s->buf_end" in flush_put_bits().
 I will upload snippets from your provided file that exhibit the issue.
