2.1 branch release debug, editor crashes

[santouits]

Operating system or device - Godot version:
Ubuntu 17.04 x86_64
Godot 2.1 branch release_debug

Issue description:
I compiled 2.1 branch with release debug option and the editor crashes randomly, or when I press control-F to search a script or when saving a scene.

On launch terminal prints:
ERROR: move_child: Invalid new child position: 2
At: scene/main/node.cpp:269.
ERROR: move_child: Invalid new child position: 2
At: scene/main/node.cpp:269.

It doesn't crash when compiling without target=release_debug

Steps to reproduce:
Attach a script and press control - F inside it, or save a scene.

Are you using GCC 6 to compile it?

[santouits]

Everything is default ubuntu.
version says
gcc (Ubuntu 6.3.0-12ubuntu2) 6.3.0 20170406
and I use this command: scons platform=x11 target=release_debug -j4

Maybe I'm doing something wrong?

[santouits]

Of course I was. For future reference:

check your version with: gcc --version
if it is 6 something: sudo apt install gcc-5 g++-5
and then compile: scons platform=x11 CC=gcc-5 CXX=g++-5 target=release_debug -j4

Either that or use clang, since we are having some GCC-6 related problems related to getting NULL this pointers...

In short, duplicate of #4623
