// Ensure that we do not export any weak symbols from the dylibs.
//
// Weak symbols require additional work from the loader to resolve the symbol at
// load time and can cause ODR violations as well as unexpected symbol
// satisfaction because the weak symbol may be used from a separate module.

// NOTE: this test is fragile.  It is dependent on the specifics of the GNU C++
// runtime.  The C++ headers from the runtime explicitly force the weak symbols
// to be publicly visible without allowing the user to control the visibility.
// We explicitly filter out the ones that we see being leaked after manually
// validating that they are being leaked because of the forceful nature of
// libstdc++.
