[Kamailio-Devel] Kamailio SVN HEAD : pv_parse_spec: error searching pvar "mb"

[Aurelien Grimaud]

I do not get it at all.

pv.so is loaded.
kamailio failed to start when using $mb variable.
in default route :
    xlog("RECEIVING : $mb\n")
in default reply route :
    xlog("default reply : $mb\n")
    xlog("default reply to initial request : $T_req($mb)\n")

I added som debug output and tried to access variables stored in same 
list as mb. i.e. $cs, $ds, $fs, $mb, ...
 My config has in its default route :
    xlog("$cs $ds $fs $mb") ;

When printing out the pvid in pv_lookup_spec_name loop, I ahve the 
following :

error searching pvar "mb"

Is not mb at the wrong place ?

There is a problem with mF insertion.
It is inserted before mb because strncmp("mF", "mb") returns > 0
But the pvids are not in such order so  the pv_lookup_spec_name fails.

There is a similar issue with $mi. pvid=24787 inserted after $fn 
pvid=27315. (because of strncmp)

And maybe with $T_branch_idx inserted after $proto (because of len)

Regards.
