Crash while saving template code

While testing some Boost code, I had experienced a reproducable crash:

Every time I comment in line 1 and 2 (see below) then save and then comment out line 2 or 1 again and save I get a crash. CB says nothing, just closes. Windows also gives no information about a crash. I've tried this some times and it's reproducable for me.

I'm using WinXP64.

Maybe it has to do with the heavy templated code of Boost an parsing symbols that use such code.

Code:

#include <boost/statechart/state_machine.hpp>

#include <boost/statechart/simple_state.hpp>

#include <boost/statechart/event.hpp>

#include <iostream>

namespace sc = boost::statechart;

struct EvStartStop : sc::event<EvStartStop> {};

struct EvReset : sc::event<EvReset> {};

struct Active;

struct StopWatch : sc::state_machine<StopWatch, Active> {};

struct Stopped;

struct Active : sc::simple_state<Active, StopWatch, Stopped> {};

struct Running : sc::simple_state<Running, Active> {};

struct Stopped : sc::simple_state<Stopped, Active> {};

int main()

{

//StopWatch myWatch; //1

//myWatch.initiate(); //2

return 0;

}

Forgot the version of CB:

I've experienced this bug in Nigthly 4875, the updated to 4893 an got the same result.

Can't reproduce here :(

But I've got crashes with my template c++ files.

The crash was somewhere in the code completion plugin

gentoo linux amd64

wx:2.8.9.2

cb:5473

Here is a backtrace from the crash (It seems to be infinite recursion in the TokensTree::RemoveToken function)
