There are bugs in your code:

  input_index += 1.0 / src_ratio ;
  filter->b_current = (filter->b_current + lrint (floor (input_index))) %
filter->b_len ;
                                                  ^^^^^ this should be 'round'
  input_index -= floor (input_index) ;
                 ^^^^^ same here.

Suppose src_ratio = 0.1 then floor (1.0 / src_ratio) can be either 9.0 or 10.0
depending on internal precision.
