Hello,
the app_jsdt and app_sqlang modules crash kamailio git master if they are
loaded together. Found by extending the "2.sh" unit test. Can be reproduced by
commenting the app_sqlang loadmodule in. Both modules load if only one of them
is loaded a time.
Core was generated by `../../src/kamailio -L ../../src/modules -Y . -P ./
kamailio.pid -w . -f 2.cfg'.
Program terminated with signal SIGSEGV, Segmentation fault.
