Hi,

I tried the signals, the code below will crash

#include <boost/signal.hpp> int _tmain(int argc, _TCHAR* argv[]) { boost::signal<int(int)> _sig; _sig(10);

return 0; }

but code below works well

#include <boost/signal.hpp> int _tmain(int argc, _TCHAR* argv[]) { boost::signal<void(int)> _sig; _sig(10);

return 0; }

The only difference is one has return value, the other doesn't, is this a bug or by design?

Sounds like a bug... could you give us more information? Compiler, platform, Boost version, etc.

I'm using win2000 pro build 5.00.2195 service pack4, Visual Studio 2003 version 7.1.3091, boost v1_31_0. And I also tested this using boost v1_32_0, also has this bug. Before crash, this assert will fail: "Assertion failed: first != last, file d:\boost_1_31_0\boost\last_value.hpp, line 23" Thanks, Wang Yun
