[reSIProcate] problems encountered during running test program testDns
resiprocate-devel，hi！
I encountered a problem of "C++ runtime abort: a pure virtual function
was called" when
running the test program testDns, and this seems to be caused by the program's
termination
before the t->thread(os/ThreadIf.cxx:33) is called. My platform is equator, and
this problem can
also be seen if you use gdb to debug it in x86 pc.
I have added some print sentences to the program.
os/ThreadIf.cxx:33
cerr << "os/ThreadIf.cxx:33" << endl;
os/ThreadIf.cxx:69
cerr << "os/ThreadIf.cxx:69" << endl;
testDns.cxx:65
std::cerr << "testDns.cxx:65" << std::endl;
-------------------------------------------------------------------------------
Direct execution of the program in x86 pc will get the following output :
$ ./testDns
os/ThreadIf.cxx:69
os/ThreadIf.cxx:33
testDns.cxx:65
Starting
-------------------------------------------------------------------------------
Run it in GDB will get:
(gdb) run

What should i do?
Any help is greatly appreciated.
