throw and catch exceptionI dont get any response on this so i will ask again
i start a new thread,
the thread instance class Foo,
Foo foo;
try {
foo.exequte();
//foo.execute throw a std::exception
}
catch(std::exception) {
}
if start one thread i catch the std::exception,
but if i run several threads the app crash.
i start the thread like this
boost::thread t(boost::bind(newthread));
appreciate any help.

I have a code like this
when execute the IdHTTPServDataEMVObj.Exequte();
it will throw a std::runtime_error
if running one thread all is fine, the catch is excequted, but if running two threads then the application crash.
What is the problem, have i miss something
appreciate any help.
