c++ - Catch exception in boost::property_tree::read_xml -

I am trying to capture the exception which is boost :: property_tree :: xml_parser :: read_xml . Here is my example program:

  #include & lt; Iostream & gt; # Include & lt; Boost / property_tree / ptree.hpp & gt; # Include & lt; Boost / property_tree / xml_parser.hpp & gt; Int main (int argc, char ** argv) {boost :: property_tree :: ptree pt; Std :: Court & lt; & Lt; "123,123" & lt; & Lt; Std :: endl; Try {std :: court & lt; & Lt; "Read" & lt; & Lt; Argv [1] is referred to as & lt; & Lt; Std :: endl; Read_xml (argv [1], PT); } Hold (const boost :: property_tree :: xml_parser :: xml_parser_error & ex) {std :: cout & lt; & Lt; Argv [1] & lt; & Lt; "Failed, Reading" & lt; & Lt; Argv [2] & lt; & Lt; Std :: endl; Read_xml (argv [2], PT); }}   
 Output is:  
  123123 read 123.xml [1] 9 7028 abort ./a.out 123.xml 345.xml   
 What am I doing wrong? Obviously the exception is not caught. I too tried to capture (...) everything through and try to catch  std :: exception  along with  boost :: exception . The result is the same in all cases. According to the promotion of the document should be thrown a xml_parser_error. My promotion version is 1.54.  
  Little update:  When I do not try to execute read_xml ("notAvalidFilePAth", pt), then I want to promote  
  After throwing an example, it is said: exception_detail :: clone_impl & lt; Boost :: exception_detail :: error_info_injector & lt; Boost :: property_tree :: xml_parser :: xml_parser_error & gt; & Gt; Can not open '(): 123.xml: file   
 and when I run it with GDB I get:  
  Read Finish 'promotion: exception_detail :: clone_impl & lt; :: exception_detail :: error_info_injector promote & lt; Promote: property_tree :: xml_parser :: xml_parser_error & gt; & Gt; '(): PATH = / usr / bin: / bin: / usr / sbin: / sbin: / usr / local / bin: / opt / x11 / bin: / usr / local / macpgg2 / bin: / opt / local / Bin: / usr / texbin: / users / weidenka / bin: can not open the file program signal received SIGABRT, has been aborted. 0x00007fff8a31b866 __pthread_kill () in # 0x00007fff8a31b866 __pthread_kill () # 1 0x00007fff86c9f35c in pthread_kill () # 2 0x00007fff86240b1a in abort () # 3 0x00000001005547d5 __gnu_cxx :: __ verbose_terminate_handler ()   
 Thanks in advance !  
 Good luck, Peter   
 
 
 This is your problem:  
  read_xml (argv [2], pt);   
 The fallback read operation is not against throwing exceptions, so when an exception occurs at this point, your program ends without flushing iostreams buffers.
