qc_dgrams_retransmit() could reuse the same local list and could splice it two times to the packet number space list of frame to be send/resend. This creates a loop in this list and makes qc_build_frms() possibly endlessly loop when trying to build frames from the packet number space list of frames. Then haproxy aborts. This issue could be easily reproduced patching qc_build_frms() function to set <dlen> variable value to 0 after having built at least 10 CRYPTO frames and using ngtcp2 as client with 30% packet loss in both direction. Thank you to @gabrieltz for having reported this issue in GH #1903. Must be backported to 2.6.
