> Project: Xerces-C++

> The class RangeToken initializes its fMap data member the first time
> on-demand, which makes it sensitive to race-conditions. I am proposing a
> patch to the class, with additional patches to the classes that perform
> static initialization to ensure that when users request full static
> initialization, the fMap data member of all static RangeToken instances is
> initialized.
> Although this does not prevent threading problems in all cases, it will fix
> the problem with all global statics. I will attempt to propose another patch
> that takes care of the problem with other uses of RangeToken.
