* And also it's easier to distribute clang for deploy to the servers.
*
* After switching from gcc 4.8 and gnu++1x to gcc 4.9 and gnu++1y (and then to gcc 5),
* an error occurred with `dlopen`: undefined symbol: __cxa_pure_virtual
*
* Most likely, this is due to the changed version of this symbol:
* gcc creates a symbol in .so
* U __cxa_pure_virtual@@CXXABI_1.3
* but clang creates a symbol
* U __cxa_pure_virtual
*
* But it does not matter for us how the __cxa_pure_virtual function will be implemented,
* because it is not called during normal program execution,
* and if called - then the program is guaranteed buggy.
*
* Therefore, we can work around the problem this way
