Hi, I'm trying build a very simple test program using ScopeExit (just downloaded from the link in the review notice: http://boost-consulting.com/vault/index.php?action=downloadfile&filename=sco pe_exit-0.04.tar.gz&directory=& ). I'm using a brand new download of Boost 1.34.1 with it. The following code builds and runs fine in release mode in both VC7.1 and 8.0, but fails to build in debug mode in both versions. I also tried specifying the BOOST_TYPEOF_COMPLIANT in MSVC7.1 debug but to no avail - I just get some other errors. I couldn't find any indication of what would cause this difference between debug/release builds. I tried disabling optimizations in release mode to check whether this would cause release mode to fail, too, but it didn't. Any help would be appreciated. Best regards, Christian Larsen Code: #include <iostream> #include <boost/scope_exit.hpp> int main(int argc, char* argv[]) { bool commit = false; BOOST_SCOPE_EXIT( (commit) ) { if( !commit ) std::cerr << "Not committed!\n"; } BOOST_SCOPE_EXIT_END //commit = true; return 0; } Building debug mode MSVC 7.1: Compiling...
