[vm/ffi] `DynamicLibrary.process()` on Android emuators #53249

Open dcharkes opened 1 year ago

dcharkes commented 1 year ago

DynamicLibrary.process() does not correctly expose symbols on the Android emulator.

A manual use of dlsym with RTLD_DEFAULT does succeed in finding the symbols after a manual dlopen with RTLD_GLOBAL. This is surprising, because the implementation of DynamicLibrary.process() is RTLD_DEFAULT.
