Description
If you type "TPointerList = array[0..High" into the editor and wait some seconds after you types
"High", the ErrorInsight parser will throw a NullReferenceException. This exception can be seen
when you debug the IDE and the debugger is configured to handle $C0000005 access
violations.
Steps to Reproduce:
1. Start RAD Studio XE2 Update 1
2. Make sure that the debugger handles the nativ OS-Exceptions Access violation ($C0000005) [Tools/Options/Debugger/Native OS-Exceptions]
3. Use "Start/Load Process..." to start another RAD Studio XE2 instance. ("$(BDS)\bin\bds.exe")
4. Create a new Delphi console application
5. Replace the code with the following code.

program High_NullReference;
type
  TPointerList = array[0..High
begin
end.

Expected:
"High" is underlined

Actual:
A NullReferenceException is thrown in the .NET ErrorInsight parser and error underlining is disabled for the whole file.
