V598 The 'memcpy' function is used to copy the fields of 'GenTree' class. Virtual table pointer will be damaged by this. ClrJit compiler.hpp 1344
struct GenTree

}
When the preprocessor variable 'DEBUGGABLE_GENTREE' is declared, a virtual function is defined. Then the class contains a pointer to the virtual method table and cannot be copied that freely.
