Method DebugCheckVersionAndDataLayout

include/imgui/imgui.cpp:10790–10801

Verify ABI compatibility between caller code and compiled version of Dear ImGui. This helps detects some build issues. Called by IMGUI_CHECKVERSION(). Verify that the type sizes are matching between the calling file's compilation unit and imgui.cpp's compilation unit If this triggers you have mismatched headers and compiled code versions. - It could be because of a build issue (using new headers w

//   Otherwise it is possible that different compilation units would see different structure layout.
//   If you don't want to modify imconfig.h you can use the IMGUI_USER_CONFIG define to change filename.
