[Boost-users] [boost test] is this a bug in Boost.Test?

Playing with Boost.Test on VC++8, I encountered something odd. This little program: #define BOOST_AUTO_TEST_MAIN #include int factorial(int n) { if(n < 1) return 1; return n * factorial(n-1); } BOOST_AUTO_TEST_CASE( factorial_test ) { BOOST_CHECK( factorial(10000) == 3 ); } Produces this output: ------- begin output ------ Running 1 test case... Press any key to continue . . . -------- end output ------ (this is debug mode, linked against libboost_unit_test_framework-vc80-mt-gd.lib): Changing "10000" to "1000" effects the correct behavior (error report). This might be related to some stack overflow issues, so if you can not reproduce this, you may want to try even greater arguments to "factorial". Is this a bug, or am I using the library incorrectly?
