I think, there are memory leaks here:

6c733e96c9/src/lib_ccx/dvb_subtitle_decoder.c (L1657-1658)

memcpy on line 1657 causes overwrites of pointers to the allocated memory:

enc_ctx->prev->buffer
enc_ctx->prev->subline
enc_ctx->prev->sbs_buffer

This memory is allocated in the function ccx_encoders_common.c::init_encoder
