Because the compiler is (usually) unable to analyze the code of an external library to determine whether it does or does not perform I/O or volatile access, third-party library calls also aren't affected by optimization. However, standard library calls may be replaced by other calls, eliminated, or added to the program during optimization. Statically-linked third-party library code may be subject to link-time optimization.

Programs with undefined behavior often change observable behavior when recompiled with different optimization settings. For example, if a test for signed integer overflow relies on the result of that overflow, e.g. `if (n + 1 < n) abort();`, [it is removed entirely by some compilers](#https://blog.llvm.org/2011/05/what-every-c-programmer-should-know_14.html) because <DocLink dest="/cpp/language/expressions/operator_arithmetic" section="overflows">signed overflow is undefined behavior</DocLink> and the optimizer is free to assume it never happens and the test is redundant.

<DocLink dest="/cpp/language/initialization/copy_elision">Copy elision</DocLink> is an exception from the as-if rule: the compiler may remove calls to move- and copy-constructors and the matching calls to the destructors of temporary objects even if those calls have observable side effects.
