// RUN:  ./dlopen-in-init3.exe

// This test uses dlopen to jump ahead in the initializer graph
// main doesn't directly link any of the libraries here, but dlopen's libfoo which links libbar and libbaz.
// We should run initializers in the order libbar, libbaz, libfoo.
// However, libbar has a static init with a dlopen of libbaz and so libbaz needs to be initialized by libbar instead of by libfoo
