Hi,

when one of the proxies receive CANCEL, 
and it also the tries to generate 408 because of frv_inv_timer timeout at
the sametime

the e2e_cancel tries to generate a response to CANCEL - 487

at this time kamailio crashes from build_res_buf_from_sip_req, 
<< for(lump=msg->reply_lump;lump;lump=lump->next) {
		len += lump->text.len; >>

is it because the 408 generated deletes the reply lump or
how can it be prevented.

thanks for looking
