First of all, it should be fstream, not ifstream. ifstreams can't write data.
Ahh, but I see you had it correct in your code anyway. You should also
specify ios::ate, ios::noreplace or ios::nocreate to make sure it is not
overwritten (you need this in Borland too, I'm positive).

However, this is a bug in GCC I believe (I had the same problem some time
back). Random file access does not work in iostreams. I didn't get any
answer about fixing it other than getting the source and recompiling GCC.
The only option I have found is to use the old C FILE streams (I actually
like these better for binary anyway).
