//! dlsym on Android KitKat (4.4.*) raises SIGFPE when searching for a
//! non-existent symbol. This wrapper avoids crashing in this circumstance.
//! https://code.google.com/p/android/issues/detail?id=61799
//!
//! The parameters and return value for this function are the same as for
//! `dlsym`, but a return value for `dlerror` may not be set in the event of an
//! error.
