Milestone:  Boost 1.38.0                        |   Component:  Python 
  Version:  Boost 1.36.0                        |    Severity:  Problem
 Keywords:                                      |  
------------------------------------------------+---------------------------
 We have a function that takes a std::string in parameter, and we wrap it
 using Boost.Python:

 void foo(string s)
 {
     cout << "foo" << endl;
 }

 BOOST_PYTHON_MODULE(mymodule)
 {
     def("foo", &foo);
 }


 When we call it under gdb, we receive a SIGTRAP signal (see attachment).
 Note that the problem disappears if the std::string is replaced by a const
 char* or if we pass a non-empty literal string. Also, it only appears
 under gdb, a normal run won't make the program crash.

 Here are the different platforms tested:
  * win32 - python2.2.3 - gcc3.4.5      - boost1.35 - gdb6.8     : KO
  * win32 - python2.5.2 - gcc3.4.5      - boost1.35 - gdb6.8     : KO
  * win32 - python2.5.2 - gcc3.4.5      - boost1.36 - gdb6.8     : KO
  * win32 - python2.5.2 - gcc4.2.1-sjlj - boost1.36 - gdb6.8     : KO
  * redhat 7.2 - python2.4.  - gcc3.3.6 - boost1.35 - gdb5.0     : OK
  * ubuntu 8.10 - python2.5.2 - gcc4.3.2 - boost1.35 - gdb6.8: OK

 So the problem seems to be reproducible only with win32.
