Hi Guys,
i've problem with my small C++ programm. I've just small template
class which represetns a array, everything works fine up to
combination with std::string. I did tried it with M$ VC++ and with GCC
(Cygwin and Linux) and my problem is when i try do this
int main(int argc, char **argv) {
array<std::stri nga(10);
a[0] = "Huhuhu"; <--- with gcc i got a crash !
std::string = a[0];
return 0;
}
the program crashes with segmentation fault on std::string::as sign(),
but just with gcc ?!
Can somebode help me solve this problem ?
