fc window exceeded

[yurigbur]

Hi,

when I try to request a large file, the following error occurs.

3.139   enc_stream_or_crypto_frame frame.c:1713 ABORT: assertion failed: 
        !enc_strm || m->strm_off < s->out_data_max 
exceeded fc window [errno 22 = Invalid argument]

I am using the lsquic client for some testing, but quant is the only server implementation where I encounter this issue.

Best

This is probably a quant bug in handling flow control updates. Unfortunately, I don't at the moment have the time to look into this.
