Place breakpoint in file SuperCallAction.cs after the call to
method = targetClass.ResolveSuperMethodNoLock(currentMethodName,
currentDeclaringModule).InvalidateSitesOnOverride().Info;
this finds the method. You can see that it is a RubyLibraryMethodInfo (i.e. a
Ruby method defined in C# library) and has two overloads (MethodBases property)
{IronRuby.Builtins.RubyIO Reinitialize(IronRuby.Builtins.RubyIO, Int32,
IronRuby.Builtins.MutableString)}
{IronRuby.Builtins.RubyIO Reinitialize(IronRuby.Builtins.RubyIO, Int32, Int32)}
This method is defined in IOOps and expects the first argument to be a file
descriptor.
If we look at File's private instance methods in MRI we see:
irb(main):004:0> File.private_instance_methods(false).sort
=> ["initialize"]
While in IronRuby we get a different result:
>>> File.private_instance_methods(false).sort
=> ["blockdev?", "chardev?", "directory?", "executable?", "executable_real?",
"exist?", "exists?", "file?", "grpowned?",
"identical?", "owned?", "pipe?", "readable?", "readable_real?", "setgid?",
"setuid?", "size", "size?", "socket?", "stic
ky?", "symlink?", "writable?", "writable_real?", "zero?"]
This means there are two bugs:
1) initialize is missing from File
2) bunch of private methods shouldn't be there
Have a fix almost ready.

Subject: [Ironruby-core] Can't subclass IronRuby libraries ("super" doesn't
resolve correctly)
I could use some help with Issue #4957
(http://ironruby.codeplex.com/workitem/4957).
Does anyone know where super class ctors are resolved? I haven't been able to
spot where they are resolved in the code.
