C++ API exception: std::length_error

Question

I used VS2019 and the compilation passed, but when I call the conn.connect() function, the following error occurred:

unhandled exception: Microsoft C++ exception: std::length_error, located at memory 0x0000000B5DAFF340.

What’s going on here?

The exception is usually caused by the following operations:

Inconsistent behavior across compilers. For example, compling the DLL with MinGW but the EXE with VS2019; compiling the DLL with g++ but compiling the EXE with VS2019
Inconsistent compilation options or linked external library versions of DLL and EXE. For example, the openSSL version, the STL version, etc.

You can refer to the environment configuration and compilation on Windows: https://github.com/dolphindb/api-cplusplus/blob/master/README.md

If the problem still exists, please send us the VS2019 configuration file to solve the problem.
