Hi,

I've had a closer look and I was too quick in dismissing your solution. however, the on_label_popped(cur_label) gets a const reference to the label. I've used a const_cast to remove the const (see code below), but now the code crashes when cleaning up the labels using deallocate. Any ideas on what could be wrong?

template void QRCSPPVisitor::on_label_popped( const Label& label, const Graph& graph ) { RCSPPVisitorData().IncrementLabelsPopped();

if ( TimedOut() || GetMillis(StartTime()) > MaxMillis() ) { this->SetTimedOut(); const_cast(label).b_is_dominated = true; } }

I think you can just change the parameter declaration to be a non-const reference. Can you please check where the crash occurs and whatever information you can get about the cause? Thanks. -- Jeremiah Willcock Hi, The crash occurs in the final loop, where you are going over vec_vertex_labels. It crashes when calling l_alloc.deallocate( (*csi).get(), 1 );. We use the standard std::allocator. Unfortunately the code has been encapsulated into a much larger project, and the only information that I have is what windows gives me: Problem Event Name: APPCRASH Application Name: QServer_D64.exe Application Version: 2013.6.6145.0 Application Timestamp: 512b792f Fault Module Name: KERNELBASE.dll Fault Module Version: 6.1.7601.18015 Fault Module Timestamp: 50b8479b Exception Code: 40010006 Exception Offset: 0000000000009e5d OS Version: 6.1.7601.2.1.0.256.1 Locale ID: 1043 Additional Information 1: 02d5 Additional Information 2: 02d5a24c112729571ddd0daf5f60defb Additional Information 3: 563e Additional Information 4: 563e19c789cadcf1ddb48080eecb0875 Removing the const from Label doesn't help, the code still crashes. So if you can put a visitor that allows to jump out of the loop prematurely that would be immensely helpful! Thanks already for the quick help. Brammert
