[Pnet-developers] ResourceReader and resgen choke on valid .resources files

[Bruno Haible]

Using pnet-0.6.0.

The ResourceReader and resgen utility choke on .resources files that
have been generated through monoresgen (or, equivalently, through
mono's ResourceWriter class).

To reproduce:

========================== hello.cs ======================
using System;
using System.Resources;
using System.Collections;
class Hello {
  static void Main () {
    ResourceReader rr = new ResourceReader("foo.mono.resources");
    foreach (DictionaryEntry entry in rr);
  }
}
=========================== foo.po =======================
msgid "Simple"
msgstr "Einfach"
==========================================================

$ cscc hello.cs -o hello.exe
$ monoresgen foo.po foo.mono.resources
Read in 1 resources from 'foo.po'
Writing resource file...  Done.
$ ls -l foo.mono.resources
-rw-r--r--    1 bruno    user          174 2003-12-28 17:56 foo.mono.resources
$ ilrun hello.exe
Uncaught exception: System.IO.EndOfStreamException: Attempt to seek beyond the 
end of the stream
        at System.IO.FileStream.Seek(Int64, SeekOrigin) in 
./System/IO/FileStream.cs
        at System.Resources.ResourceEnumerator.MoveNext() in 
./System/Resources/ResourceReader.cs
        at Hello.Main()

$ resgen foo.mono.resources foo2.po
foo.mono.resources: invalid offset to resource value
