The fragile binary interface problem or FBI is a shortcoming of certain object-oriented programming language compilers, in which internal changes to an underlying class library can cause descendant libraries or programs to cease working. It is an example of software brittleness.
For example, an interpreter may document a particular behavior for some operations that are undefined in the language specification, while other interpreters or compilers for the same language may not. A compiler produces executable code for a specific ABI, filling the semantic gap in ways that depend on the compiler version: the documentation ...
32-bit compilers emit, respectively: _f _g@4 @h@4 In the stdcall and fastcall mangling schemes, the function is encoded as _name@X and @name@X respectively, where X is the number of bytes, in decimal, of the argument(s) in the parameter list (including those passed in registers, for fastcall).
Depending on the compiler and architecture, it also may be the case that calling conventions differ between the two languages. For these reasons, for C++ code to call a C function foo(), the C++ code must prototype foo() with extern "C". Likewise, for C code to call a C++ function bar(), the C++ code for bar() must be declared with extern "C".

In the example above, the compiler might insert a move from y 1 to y 3 at the end of the middle-left block and a move from y 2 to y 3 at the end of the middle-right block. These move operations might not end up in the final code based on the compiler's register allocation procedure.
The effect of the as-if rule depends on the specific compiler implementation. As an example, in the Microsoft Visual C++ compiler, it causes omission of certain optimizations such as instruction reordering around calls to library functions, since such calls may cause input/output actions or accesses to memory locations marked volatile, and ...
Haxe is a general-purpose programming language supporting object-oriented programming, generic programming, and various functional programming constructs. Features such as iterations, exceptions, and reflective programming (code reflection) are also built-in functions of the language and libraries.
