Crash on VS2005

[kbw]

I've just started looking at Poco and have been seeing a weird crash on Visual Studio 2005. I have a minimal sample that reproduces this crash. The crash always happens on the first line in Process on the third (recursive) call in to Process.

I believe my Runtime Library Settings are correct, I''ve double checked them against the poco Visual Studio project settings, Multi-threaded Debug DLL (/MDd) for debug builds. I've rebuild poco just to be sure the libs are correct.

It does work correctly under Visual Studio 2008. My guess is there's some build/link issue resulting in some incompatibility between the C++ runtime libs--but I'm not sure how to resolve this. I've not seen this sort of problem with VS2005 before.

Can anyone shed any light on what's going on here? Thanks.

Code: Select all

#include <Poco/Path.h>
#include <Poco/DirectoryIterator.h>

void Process(const Poco::Path &path, const std::string &file)
{
   std::string filename = path.toString() + file;   

   for (Poco::DirectoryIterator p(path); p != Poco::DirectoryIterator(); ++p)
   {
      if (p->isDirectory())
      {
         Process(p->path(), file);
      }
   }
}

int main()
{
   Process("C:\\Temp\\", ".MAP");
   return 0;
}

It also crashes under VS2003. Here's the call stack.

Just to rule out the obvious issue: you for sure have compiled POCO with the same Visual Studio version as your application? Linking POCO DLLs built with VS2008 to an application linked with VS2005 or VS2003 won't result in anything useful...

It's all my fault!

I had previously installed the Commercial vs2008 version and it was in the path. I've fixed that and the VS2003 build is happy now. I expect the VS2005 build will be too. I'll post my confirmation once I've tested it.

Thanks.
