Okay, I figured it out, I'm trying to link application in Debug configuration with connector libraries that looks like in Release mode, when I compile connector from sources in Debug configuration - error disappear.
Description: When I pass connection URL to mysqlx::Client or server information to mysqlx::Session - connector are crashing. Debugging shows, that when string object (with url in case of mysqlx::Client, and host/user/password in case of mysqlx::Session) passes to the "string::Impl::from_utf8" it corrupts for some reason, that cause constructor of "cdk::string" to throw an exception of "bad allocation". Tested systems (As Virtual Machines in VirtualBox Version 6.0.0 r127566): - Windows 10 Pro (1809, Build 11763.168) 10.0.17763 N/A Build 17763 - Windows 10 Pro (1809, Build 11763.1) 10.0.17763 N/A Build 17763 As native: - Windows 10 Enterprise (1709, Build 16299.125) 10.0.16299 N/A Build 16299 Error appears in Debug configuration, application in Release is working fine without any problems. How to repeat: Download official MSDN image of Windows 10 Pro (en_windows_10_business_edition_version_1809_updated_sept_2018_x64_dvd_d57f2c0d for e.g.), install Microsoft Visual Studio Enterprise 2017 Version 15.7.5 (VisualStudio.15.Release/15.7.5+27703.2042) and try to run simple application in Debug configuration (x86): mysqlx::Session sess("<host>", 33060, "<user>", "<port>"); or mysqlx::Client client("mysqlx://<user>:<password>@<host>/<db>", mysqlx::ClientOption::POOL_MAX_SIZE, 4);
