Possible bug: ostringstream
Hi All,
I have come across a bug associated the following code, it work fine in
VS2008 release mode and crash in debug mode, I did some research found
it should be a bug in the microsoft implementation of ostringstream, Is
anybody know how to fix this or alternative way? Any ideas would be
appreciated.
BTW: I must use std::ostringstream because actually lot of dependencies
dll was developed with std::ostringstream.str() return. I don't want
change the dependencies project it wastes too much.
std::string result( "" );
size_t length = source.size();
std::ostringstream offset;
long offsetsToSource = 12135L;
offset << offsetsToSource;
std::string nsource = offset.str();
result.reserve( nsource.length() * 1.6 );
std::for_each( nsource.begin(), nsource.end(),ToXML( result, "\"&<>" )
);

Um. What exactly does this have to do with Boost? In Christ, Steven Watanabe
It didn't related Boost in following piece of code, but I know some guys was discussed the similar issue in this mail list before, so I want get help from there.

Jammy, Please don't top post in this list. It's highly unlikely there's a bug in ostringstream. I suggest you shorten your code bit by bit and then you'll home in on the problem. Write out the std::for_each() as a for loop. What you want to get to is a minimum size program that exhibits the problem. Just doing that will probably help find the error which I'll wager is with your code. If you have a nice *small* program that shows the problem, then post this to comp.lang.c++ newsgroup (you can access that through Google Groups) and they'll help you out. Also, take a good look at the stack trace! Pete
