I have an application that is using the boost filesystem library. Here is a snippit of the code :

void DirectoryInterface::listSubDirectories(String dirPath, FileList & dirList)
{
   pthread_rwlock_rdlock(&DirectoryInterface::fsRwMutex);

   try
   {
      boost::filesystem::path filePath(dirPath, boost::filesystem::native);
      boost::filesystem::directory_iterator iter(filePath), iterEnd;

      if(boost::filesystem::exists(filePath))
      {
         for (; iter != iterEnd; ++iter)
         {
            
            if(boost::filesystem::is_directory(*iter))
            {
               .. do something
            }
         }
      }
   }
   catch (boost::filesystem::filesystem_error& ex)
   {
      .. do something
   }
   catch (std::exception& ex)
   {
      .. do something
   }
   catch (...)
   {
      .. do something
   }

   pthread_rwlock_unlock(&DirectoryInterface::fsRwMutex);
}

An exception is thrown by the call to boost::filesystem::is_directory() but is not caught by any of the catch blocks shown here. The application simply terminates with the following message :

terminate called after throwing an instance of 'boost::filesystem::filesystem_error'
  what():  boost::filesystem::is_directory: "/opt/users/tmackinn/neDatabases/20060429050000.auto/10.1.26.25": No such file or directory
Abort - core dumped

Any ideas what I could be doing wrong?

Thanks in advance,
