[Bug c/23054] New: Segmentation fault when large static array is declared

[relf at os2 dot ru]

The following program causes Segmentation fault being compiled with
gcc (GCC) 4.0.1 (Debian 4.0.1-2)

#include <stdio.h>
int main() {
    char A[ 1UL << 24 ];
    A[0] = 0;
    puts("OK");
    return 0;
}

$ gcc test.c
$ ./a.out
Segmentation fault

If array of the same size (16M) is dinamically allocated (e.g., via malloc())
everything works as expected.

debian-amd64 with 4G physical memory here.

This is not a bug.  You are overflowing the stack.  You either can use malloc
or raise the stack limit.

Should it be more intelligent error message like "Stack overflow" ?

That is still not a GCC bug, report this enhancement to the OS you are using since that is where the 
message is comming from.
