Cygwin - IO 2006-09-20 - Seg fault

Hello,

I compiled IO 2006-09-20 using Cygwin on Windows XP. By the way I had to fix the Makefile.lib, and could you modify libsiovmsourceIoSystem.c:

by replacing
  ;  #if defined(unix) || defined(__APPLE__) || defined(__NetBSD__)
by
    #if !defined(__CYGWIN__) && (defined(unix) || defined(__APPLE__) || defined(__NetBSD__))


By running the following program, I got a segfault:
iterator := Object clone do (

bailout := 16
max_iterations := 1000

mandelbrot := method (x,y,
    cr := y - 0.5
   ; ci := x
    zi := 0.0
   ; zr := 0.0
   ; i := 0
   
    while (1,
   ;     i = i + 1
        temp := zr * zi
        zr2 := zr * zr
        zi2 := zi * zi
        zr := zr2 - zi2 + cr
        zi := temp + temp +ci

        if (zi2 + zr2 > bailout,
            return i)
        if (i > max_iterations,
 ;           return 0)
    )
)

print_set := method (
    writeln("Rendering...")   
    for(y, -39, 39,
   ;     write("n")
        for(x, -39, 39,
   ;         i := mandelbrot(x/40.0,y/40.0)
    & nbsp; ;      if (i == 0, write("*"),write(" "))
   ;     )
    )
)
)

"" println
time := Date cpuSecondsToRun(iterator print_set)
"Io Elapsed # secs" println

Here is the segfault:
