Summary: stl port 5.2.0 & exceptions & crash

Initial Comment:
copy-paste from dev. forum follows:

Hello guys, 
 
I recently upgraded from STLPort 5.0.2 to 5.2.0. 
The result is that my program crashed in boost 1.33 on exception handling. 
 
Digging further, I found out that __Named_exception class is a culprit. 
__Named_exception class was changed to contain dynamically allocated char * member. 
 
So copy constructor and assignment operators generated by the compiler are not going to do their job right any more. 
I think that __Named_exception has to implement copy ctor and assignment operators to support for exceptions when they are passed to catch() by value: 
 
Consider the following code from e.g. 
boost_1_33_1\boost\date_time: 
 
struct bad_month : public std::out_of_range 
{ 
bad_month() : std::out_of_range( 
std::string("Month number is out of range 1..12")){} 
}; 
 
try { 
throw bad_month();  
} 
catch(out_of_range ex) { //ups! correct copy ctor must be called here! 
} 
 
just in case, my compiler is MS VC 8.1. But I don't think it matters. 
 
Regards,

You are perfectly right, thanks for reporting this issue before 5.2 gets released. It would be great if you could create a bug entry in our bug tracking system.
