Another issue reported on the Boost user's list:

Hi there, I'm trying to run http_client.cpp taken from the netlib
examples. But unfortunately it's throwing a lot of exceptions.

The line:

cout << body(response) << endl;

results into the following exceptions:

First-chance exception at 0x000007fefdd0aa7d in test_netlib_vc10.exe:

I'm using boost trunk with Visual Studio 10 compiling x64 bit code.

Anyone any idea what going on here?

Thanks,
