[lwip-users] Pbuf assertion failure

[Etienne Lanoy]

Yes I'm using Altera Nios but I have search the patch for the Data cache 
bug but
I've not found it.

I'm very desagree because in all my software I do the same action 
tcp_write and after
tcp_output. There is no problem. Maybe something is broken in my 
software but
I haven't any idea what can produce this assertion failure.

I thank you a lot for your help.

Best regards,
Etienne
