Hi,
the following drives my mad:
---8<---
class CommandLineOptions {
public:
CommandLineOptions( int argc, char** argv );
bool option( const std::string& arg ) const;
...
private:
po::options_description generic_options;
po::options_description hidden_options;
po::options_description usage_options;
po::options_description cmdline_options;
po::positional_options_description pos_options;
po::variables_map vm;
};
--->8---
---8<---
bool CommandLineOptions::option( const std::string& arg ) const
{
return vm.count( arg );
}
--->8---
int main( int argc, char **argv )
{
try {
CommandLineOptions cmdline( argc, argv );
running using gdb (on return of main()):
Program received signal SIGSEGV, Segmentation fault.

Each time it crash in ~variables_map. Is it a bug??
I'm using gcc-Version 4.2.3 20080114 (prerelease) (Debian 4.2.2-7)
Thanks,
