Details - When loading data from a simple MySQL table into mtree, kamailio segfaults on start.
I see the following error when loading the core dump into gdb:
<code>
Core was generated by `/usr/sbin/kamailio -P /var/run/kamailio.pid -u kamailio -g kamailio -f /etc/kam'.
Program terminated with signal 11, Segmentation fault.
#0 __strlen_sse2 () at ../sysdeps/x86_64/multiarch/../strlen.S:31
31 ../sysdeps/x86_64/multiarch/../strlen.S: No such file or directory.</code>
Here's the backtrace from kamailio:

here's the mtree parameters in my config:
<code># ----- mtree params ------

modparam("mtree", "db_table", "mtree")

modparam("mtree", "pv_value", "$avp(s:didmatch)")
modparam("mtree", "mt_ignore_duplicates", 1)

and Kamailio was compiled with the following options:
<code>make -j3 CC=x86_64-pc-linux-gnu-gcc CPU_TYPE= SCTP=0 CC_EXTRA_OPTS=-I/usr/gnu/include mode=release TLS_HOOKS=0 FLAVOUR=kamailio group_include='kxml kstandard kmysql' include_modules='mi_fifo regex sipcapture siputils statistics textops textopsx tm uac uac_redirect xlog' exclude_modules=iptrtpproxy prefix='/usr/' all</code>
Here's MySQL structure and sample data:
<code>mysql> desc mtree;
+-------------+---------------------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+-------------+---------------------+------+-----+---------+----------------+
| id | int(10) unsigned | NO | PRI | NULL | auto_increment |
| phonenumber | bigint(20) unsigned | NO | UNI | NULL | |
| value | tinyint(1) | NO | | 1 | |
+-------------+---------------------+------+-----+---------+----------------+
mysql> select * from mtree limit 3;
+----+-------------+-------+
| id | phonenumber | value |
+----+-------------+-------+
| 1 | 2267800202 | 1 |
| 2 | 2267800203 | 1 |
| 3 | 2893400187 | 1 |
+----+-------------+-------+
</code>
I verified there are no NULL values in the table.
