Is there any way a C/C++ program can crash before main()?

Hi, I have one question... Is there any way a C/C++ program can crash before main()? Regards, Mbatra

The question is unclear: are you asking about compilation order?

int x = ;
int main()
{
return 0;
}

this will not compile, error is before main

there are no facts, only interpretations

Hi, My question was: Is there any way a C/C++ program can crash before main()? Like when u run your program, it crashes even before it starts to execute main.. Regards, Mbatra

Yes, it is possible, but without more details it is impossible to guess why.

Use the best guess

The initialization of your static variables are performed before main() and their deinitialization is performed after main() returns or after the exit() call. If you put buggy code in there then you can easily crash before/after main().

Yes ! A c/c++ program will crash when it can't find a necessary library.

Here is a cooked-up example:

#include
using namespace std;

class Crash
{
public:
Crash()
{
int *a = new int[5];
for (int i = 0; i < 7; ++i)
{
a[i] = 25;
}
delete[] a;
}
};

Crash crash;

void main()
{
cout << "If ever I come here ..." << endl;
}

This program will crash even before entering main().

Yes, it can if the program didn't find dependency libraries in the search paths.
