1685899 - xpidl.py enters an infinite loop when a constant symbol is not found

Status: RESOLVED FIXED

(Core :: XPCOM, task)

Description

[Masatoshi Kimura [:emk]]

Steps to reproduce:

#include "nsISupports.idl"
[uuid(7e4c52f2-bece-41b9-8695-27f1240beda9)]
interface nsIFoo : nsISupports {
  const unsigned short X = Y;
};

Actual result:
Build hangs and 100% CPU usage because of an infinite loop.

Expected result:
An error message such as:

 0:13.74 xpidl.xpidl.IDLError: error: cannot find symbol 'Y', f:/m/mozilla-unified/dom/interfaces/base/nsIFoo.idl line 4:27
 0:13.74   const unsigned short X = Y;
 0:13.74                            ^
