Dear list,
I've started using Boost.Python to wrap a 3rd party C++ library, and
whilst running my unit tests, the Python interpreter segfault's during
garbage collection.
With explicit object deletion:
$ gdb -q --args python -c 'import mylib; obj = mylib.MyObj(); del(obj)'
...
*** Error in
Hi,
I was wondering the best way to solve this problem:-
void WrapperClass::parse_args(boost::python::list argv)
{
int argc = boost::python::len(argv);
const char* const* pargv = boost::python::extractconst*>(argv); /// <
WrappedClass::parse_args(argc, pargv);
}
This doesn't wo

Can you send the C++ code of MyObj? Kind of hard to diagnose a
C++-side crash without any C++ code.

Sure. Sorry, thought previous email was getting long and it might have been an obvious fix for someone... Just writing a

This could be misinformation, but some of the boost libraries have
compile time flags that depend on whether or not threading is enabled.
As an example, I was running into issues with an invalid free() with
respect to shared_ptr (in the cctbx project). Unfortunately, (for your
case) the fix wa

First problems is as follows. I have the following piece of python code:
inv = ActiveGame.GetPlayerParty().GetInventory().GetItems()
print str(len(inv))print type(inv)inv["Th
