C Run-Time Error R6030
CRT not initialized
This error occurs if you are using the CRT, but the CRT startup code was not executed. It is possible to get this error if the linker switch /ENTRY is used to override the default starting address, usually mainCRTStartup, wmainCRTStartup for a console EXE, WinMainCRTStartup or wWinMainCRTStartup for a Windows EXE, or _DllMainCRTStartup for a DLL. Unless one of the above functions is called on startup, the C Runtime will not be initialized.
Process needed to troubleshoot issue.
If the /ENTRY switch is not used then what steps can I use to identify the cause of the issue?
