    provider_def.h:line#: warning: parameter names (without types) in function declaration

  • Multi-threaded processes under ustack(), usym(), uaddr() and umod(), which perform dlopen() in threads other than the first thread might not have accurate symbol resolution for symbols introduced by dlopen(). (Bug ID 20045149)
