 Replying to [comment:3 eckhardt]:
> Now, what I still don't know is what exactly you are seeing. Is
 STLport's debug mode throwing an out-of-bounds access or is something else
 failing? Can you provide some code that fails?

 In this code, when str is "1024", sometime it returned 1024, sometime 1 :

 {{{boost::lexical_cast< unsigned >( str );}}}

 The change I provided fixed that.

> Lastly, STLport 5.0.0 was released 2005-11-02! That's almost four years
 ago! Further, since I partially maintained the STLport port to MS Windows
 CE, I know that there is actually a test-case for the above behaviour,
 though I'm not sure when exactly the test was added and (possibly) the
 behaviour fixed. If I were you, I would consider upgrading, at least to
 the last 5.0 release. OTOH, current compilers usually come with a well-
 working C++ stdlib, so just using the native one would make things easier

 Probably we should upgrade STLPort. We are using STLPort in a cross-
 platform project, and on some platforms some features are not available
 with the C++ compiler.
