I'm guessing you allocated this as an 'automatic', IOW on the stack. Your
exe probably has a maximum stack size of 1MB. So bang.

Simplest would be to make your stack bigger, this is usually a linker option.

Or allocate on the heap, this is the proper choice but you are going to
enter a really dark cavern if you go this way.

Try,

char (*loglines)[256] = new char [4096][256] ;

use as you would your declaration and at the end it's polite to call,

delete [] loglines ;

You can vary the 4096 at run time.

I need to say that this is not the right approach, you should create a
std::vector of std::string. But I guess this isn't covered yet. Have fun
debugging...
