Initialization of OA (oa_2) structure in function build_oa_soap_custom_handler() is incorrect.
File: "plugins/oa_soap/oa_soap.c"
164 oa_handler->oa_2->mutex = wrap_g_mutex_new_init();
165 memset(oa_handler->oa_1->server, 0, MAX_URL_LEN);
166 oa_handler->oa_2->oh_handler = oh_handler;
Fixed in checkin #7621
