2555,"SIGTRAP received while calling a wrapped function with """"",bruno dot lalande at gmail dot com,Dave Abrahams,"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.
