Exception from while(){}

Was doing a typical
Code: Select all
while()
to iterate through the lines of a file and received the following message:

An exception has been encountered. This may be caused by an extension.


Here's the relevant entry in the ActivityLog:

Code: Select all
System.NullReferenceException: Object reference not set to an instance of an object.
   at    
 	.
 
 .VisitWhileStmt(WhileStmt x)
   at Devsense.PHP.Syntax.Ast.WhileStmt.VisitMe(TreeVisitor visitor)

   at Devsense.PHP.Syntax.TreeVisitor.VisitGlobalCode(GlobalCode x)
   at

   at    
 	.(GlobalCode

 )

 , ITextVersion 	 		)
   at PHP.VisualStudio.Language.Editor.Outlining.BlocksFromAstTagger.
.InvokeTask()
   at PHP.VisualStudio.Language.TaskQueue.
.
 ()
--- End of stack trace from previous location where exception was thrown ---
   at Microsoft.VisualStudio.Telemetry.WindowsErrorReporting.WatsonReport.GetClrWatsonExceptionInfo(Exception exceptionObject)


And finally, the code that caused it all...

Code: Select all
$fh = @fopen($file, 'r');

if ($fh) {
   while (($buf = ))
}
