problems with fh:read()

[Markus Huber <pulse@...>]

The problem seems to occure only with Linux (the problem doesn't occure
with FreeBSD / Mac OS X). The first example works fine also with Linux:

   fh,err=io.open("./Dummy","w+")
   if err then print(err) end
   
   fh:write("A")
   fh:write("B")
   fh:write("C")

   fh:close()

Show File: --> ABC as expected

But if I add a simple read() the return of read and the resulting file
and are wrong.

   fh,err=io.open("./Dummy","w+")
   if err then print(err) end
   
   fh:write("A")
   fh:write("B")
   fh:write("C")
   
   print(fh:read("*a")) --> this example returns an empty string
   
   fh:close()

Show File: --> <0 bytes> but should be also ABC

   fh,err=io.open("./Dummy","w+")
   if err then print(err) end

   fh:write("Abc")
   fh:write("Def")

   fh:seek("set",1)

   fh:write("Ghi")

   print(fh:read("*a"))

   fh:close()

Show File: --> AbcDef but should be AbcGhi
