managed_shared_memory constructor crash

[seppleviathan@…]

The following code causes a crash on Visual Studio 2013 when compiling for 64-bit and with optimization.

#include <boost/interprocess/managed_shared_memory.hpp>

using namespace boost::interprocess;
int main()
{
  static const char name[] = "test_shm";
  shared_memory_object::remove(name);
  managed_shared_memory segment(create_only, name, 65536);
  return 0;
}

The reported error is a buffer overrun The crash doesn't happen on 32-bit builds. It also doesn't happen when building without optimization. Finally, it doesn't happen when compiling with /GS- (disable security checks).

This is the stack trace:

We are also experiencing what appears to be an identical problem using Boost 1.55 and VS2013, we are also making 64Bit optimised builds when we see this problem. Changing back to Boost 1.51 or using VC10 seems to work fine - Roger

[Ion Gaztañaga]

This seems solved in current develop and master branches. Could you check this?

[seppleviathan@…]

Yes, this seems to be fixed in master. Thanks!
