[Boost-users] [system] in multi-threaded context

Hello,

I have some problems with the latest changes to asio, which turn out to 
be caused by problems with boost::system. The newer versions of 
boost::asio now use boost::error_code provided by boost::system for 
error handling.

On OS X 10.4 with XCode 2.4.1 comparing two boost::error_code objects e1 
& e2 always returns false. I believe this is caused by comparing objects 
accross threads. But this is just a guess. A problem I noticed on with 
Apple's version of gcc is that static instance variables behave strange, 
there seems to be a copy for each variable in each compilation unit that 
uses them? This may also somehow be the cause for my problems with 
boost::system.

Another problem is that when I receive an error_code object, say e, from 
asio, trying to print e.message() fails with an access violation. This 
happens on Windows, Linux, OS X.

What am I doing wrong?

Thanks,
