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.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.
