Assembly: Push the stack over

How much data can you push on to the stack before your program falls over?

Let's have a look then...

program stack_zapper;

#include( "stdlib.hhf" )

// Phil Gardner

begin stack_zapper;

    stdout.put( nl );
    stdout.put( "Repeatedly push 4 byte value on to the stack." );
    stdout.put( nl );

    mov( $0000029A, eax );

    stdout.put( "eax = " );
    stdout.put( eax );
    stdout.put( nl, nl );

    mov( $00000000, ebx );

infiniteLoop:

    stdout.put( "Stack pointer = " );
    stdout.put( esp );
    stdout.put( nl );

    mov( $00004000, ecx );

pushBigChunk:

    push( eax );

    dec( ecx );

    jge pushBigChunk;

    stdout.put( "Pushed another 16 KB on to stack" );
    stdout.put( stdio.tab );

    inc( ebx );

    stdout.put( ebx );
    stdout.put( " x 16 KB" );
    stdout.put( stdio.tab );

    jmp infiniteLoop;

end stack_zapper;
