As Siva mentioned, it does in fact impact the ABI. A class with a non-trivial destructor is not a POD, and affects the calling convention, so the debugger needs to know the difference. C++ ABI reference here: http://mentorembedded.github.io/cxx-abi/abi.html#return-value I've submitted a DWARF proposal to document the use of the DW_AT_artificial attribute on a default copy constructor or destructor. -cary
