Hello all,
A function throws boost::exception as follows:
//.... typedef boost::error_info
action_name; BOOST_THROW_EXCEPTION(error() << action_name(name)); return 0; Both BOOST_NO_EXCEPTIONS and BOOST_EXCEPTION_DISABLE are *not* defined. The excpetion is not catched anywhere. However, the thread continues running! If I put breakpoint at "return 0;" it's hit, and I can continue stepping the code. I run the program under MSVC 9.0, in debug mode, and I see "First-chance exception" and "Unhandled exception" notifications issued by the debugger. Isn't it wrong behavior, or I miss something?
Since the debugger tells you that the exception has been thrown, the only way to get the behavior you're observing is if you catch it. Try setting a break point in your exception's destructor. Since you're deriving from boost::exception, you can set the break point at boost::~exception(), in boost/exception/exception.hpp, line 254. It should hit at the closing } in the exception handler.

Well, it also tells me that the exception is unhandled(!)... but the thread survives: First-chance exception at 0x7c812aeb (kernel32.dll) in XXX.exe: Microsoft C++ exception: boost::exception_detail::clone_implMyNamespace::error at memory location 0x0529a500.. Unhandled exception at 0x7c812aeb (kernel32.dll) in XXX.exe: Microsoft C++ exception: boost::exception_detail::clone_implMyNamespace::error at memory location 0x0529a500..

The ~exception() is called several times (probably the exception object is copied) at the closing "}" of: throw_exception.hpp: template<class E> inline void throw_exception( E const & e ) Then the execution proceeds to the breakpoint at the line after BOOST_THROW_EXCEPTION

Can you put this in a self-contained program? -- Emil Dotchevski Reverge Studios, Inc. http://www.revergestudios.com/reblog/index.php?n=ReCode
