How can I successful compile the following sample using BCC?

Code (fw): Select all Collapse
char Array[ 68000000 ][ 5 ];

    return 0;
}


I get the followin error message:

Fatal: Out of memory

Enrico,

Why don't you allocate memory dinamically in runtime using hb_xgrab() ?

It is the right way to do it or you run out of stack memory

Antonio,

I know about dynamic allocation but I asked specifically for static allocation that doesn't use heap or stack.

I guess that you may have found a Borland bug

You could try it with Visual C++ and see what happens

Antonio,

I've already tried with another C compiler and got no error message.

Then it confirms it is a Borland bug

Anyhow I don't see it as dangerous one for the apps
