Hi Wolfgang,
it seems the code I have was modified. I look in the original cvs version and it seems that the base address isn't restored either.
[...] addr = base; save[i] = *addr; <-- save value at base address *addr = 0; <--- modify it.
if ((val = *addr) != 0) { <--- error case : restore all values [...] }
<-- we forget to restore the value and start to restore value @base+1 with save[i-1].
for (cnt = 1; cnt < maxsize / sizeof (long); cnt <<= 1) { addr = base + cnt; /* pointer arith! */ val = *addr; *addr = save[--i]; if (val != ~cnt) { size = cnt * sizeof (long); /* Restore the original data before leaving the function. */ for (cnt <<= 1; cnt < maxsize / sizeof (long); cnt <<= 1) { addr = base + cnt; *addr = save[--i]; } return (size); } }
regards,
Matthieu
