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
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;
}
