Miranda is crashing right after connecting protocols to the network. Tried also with older BClist and same problem. Without BClist is working normally. In the attachment there is full crash log and mdmp file. Used debug simbols by updating everything after disabling BClist in DBEditor++. After updating, enabled it again and CrashDumper created this report.
P.s. Guessing the problem appears from 15652 where are changes related to STDClist and some code has been moved from core to the plugin.
