The following program generates segmentation fault when exception is thrown from
constructor. The fault happens if type of CONTAINER is std::list or std::set,
but does not happen if its type is std::vector or if CONTAINER is ommited from
TST class. Also tested on linux with same resutls.
---- Program source:-----------------
#include <list>
class TST {
std::list<int> CONTAINER;
public:
TST(int i) {
if (i==0) {
delete this;
throw 1;
}
}
~TST() {
printf("Destructor\n");
}
};
int main() {
TST* tst = NULL;
try {
tst = new TST(0);
}
catch (int i) {
printf("Caught %d\n",i);
}
if (tst != NULL)
delete tst;
}
