command line arg --substdefs doesn't work anymore

[seven1240]

Description

with the following args

--substdefs=/S_KAM_IP_PUBLIC/$KAM_IP_PUBLIC/ \
--substdefs=/S_KAM_SIP_PORT/$KAM_SIP_PORT/

error logs when start

 0(24400) ERROR: <core> [core/ppcfg.c:57]: pp_def_qvalue(): defined value is too large 0 < 15
 0(24400) ERROR: <core> [core/ppcfg.c:192]: pp_substdef_add(): failed to enclose in quotes the value
 0(24400) ERROR: <core> [main.c:2371]: main(): failed to add substdefs expression: /S_KAM_IP_PUBLIC/192.168.7.8/

Troubleshooting

the first log was reported with this pr

#3151

so looks like pv_get_buffer_size() returns 0, and there looks like nowhere called pv_set_buffer_size().

I can confirm the same args works with the docker image: kamailio/kamailio-ci:5.4.4-alpine.

the following config works in kamailio.cfg, so only the command line arg has problem.

#!substdef "!HOMER_DB_USER!homer_user!g"
#!substdefs "/ID/subst/"

Reproduction

add the following arg to command line when kamailio start

--substdefs=/ID/VALUE/
