This started happening with 5.8.0. I was to update our project with Docker image from 5.7.1 to 5.8.0

``` kamailio[594]: ERROR: acc [acc_extra.c:169]: parse_acc_extra(): parse failed in <callid=$dlg(callid);src_user=$(dlg(from_uri){uri.user});dst_user=$(dlg(to_uri){uri.user});xxx_channel_id=$dlg_var(xxx_channel_id);t_error=$dlg_var(to_original_user);src_original_user=$dlg_var(from_original_user);dst_original_user=$dlg_var(to_original_user)id);src_user=$(dlg(from_uri){uri.user});dst_user=$(dlg(to_uri){uri.user});xxx_channel_id=$dlg_var(xxx_channel_id);t_error=$dlg_var(to_original_user);src_original_user=$dlg_var(from_original_user);dst_original_user=$dlg_var(to_original_user> around position 257 kamailio[594]: ERROR: acc [acc_extra.c:173]: parse_acc_extra(): error kamailio[594]: ERROR: acc [acc_cdr.c:827]: set_cdr_extra(): failed to parse crd_extra param kamailio[594]: ERROR: acc [acc_mod.c:528]: mod_init(): failed to set cdr extra 'callid=$dlg(callid);src_user=$(dlg(from_uri){uri.user});dst_user=$(dlg(to_uri){uri.user});xxx_channel_id=$dlg_var(xxx_channel_id);t_error=$dlg_var(to_original_user);src_original_user=$dlg_var(from_original_user);dst_original_user=$dlg_var(to_original_user)id);src_user=$(dlg(from_uri){uri.user});dst_user=$(dlg(to_uri){uri.user});xxx_channel_id=$dlg_var(xxx_channel_id);t_error=$dlg_var(to_original_user);src_original_user=$dlg_var(from_original_user);dst_original_user=$dlg_var(to_original_user' kamailio[594]: ERROR: <core> [core/sr_module.c:1039]: init_mod(): Error while initializing module acc (/usr/lib/x86_64-linux-gnu/kamailio/modules/acc.so) ```

This is how it looks in cfg: ``` modparam("acc", "cdr_extra", "callid=$dlg(callid);src_user=$(dlg(from_uri){uri.user});dst_user=$(dlg(to_uri){uri.user});" "xxx_channel_id=$dlg_var(xxx_channel_id);t_error=$dlg_var(to_original_user);" "src_original_user=$dlg_var(from_original_user);dst_original_user=$dlg_var(to_original_user)")

```

I have tested and it looks like it only happen if cdr_extra fields are bigger > 255 char.
