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