ofxLua projects compiled for debugging crashes on start

Bringing this over from #57

Hi, I just tried to run luaExample on Arch Linux and it crashes silently. In the debugger I see this:

1  glm::vec<4, float, (glm::qualifier)0> glm::operator *<float, (glm::qualifier)0>(glm::vec<4, float, (glm::qualifier)0> const&, float const&)                                                                                   type_vec4.inl                                                                          866  0x5555559444d8

I'm just running luaExample unmodified, I don't know which script it is running. It's my first attempt at ofxLua. This is the output:

10:29:25: Starting /home/fp/src/openFrameworks/addons/ofxLua/luaExample/bin/luaExample_debug ...
ANOM_ABEND auid=1000 uid=1000 gid=1000 ses=1 pid=22528 comm="luaExample_debu" exe="/home/fp/src/openFrameworks/addons/ofxLua/luaExample/bin/luaExample_debug" sig=11 res=1
10:29:25: The program has unexpectedly finished.
10:29:25: The process was ended forcefully.
10:29:25: /home/fp/src/openFrameworks/addons/ofxLua/luaExample/bin/luaExample_debug crashed.

So it compiles fine and closes immediately. Can I help figure it out?

update: based on this

    scripts.push_back("scripts/graphicsExample.lua");
    scripts.push_back("scripts/imageLoaderExample.lua");
    scripts.push_back("scripts/polygonExample.lua");
    scripts.push_back("scripts/fontsExample.lua");
    currentScript = 0;

it is running graphicsExample.lua. Changing currentScript to 1, 2 or 3 also crash.

@hamoid Does it crash if there are "no scripts" run? ie. comment out doScript() in ofApp::setup()

[hamoid]

Hi! It does still crash. One by one I removed all lines the lines that have something to do with lua and it still crashes. Then I realized it crashes inside ofSetupOpenGL(1024, 768, OF_WINDOW); as soon as the addon is included in the qbs file (QtCreator):

    of.addons: [ 'ofxLua' ]

If I remove the addon then it runs. Is the addon maybe redefining something that breaks glm?

So it also crashes at the vec4 multiplier...

[jildertviet]

Ah, compiling without XCode (11.6), and just using make works...

[danomatika]

@jivido Sometimes I see that in Xcode and simply re-run the build a couple times, then it will build ok. It's weird, I know... all that C++ templating black magic. Scratch that, you're referring to a run time crash as opposed to compile error?

[jildertviet]

Ah, building in Release mode also works! However, rebuilding the Debug version doesn't seem to work...

[danomatika]

As a follow up, I see this all the time and simply test in release mode. Still not sure why the debug build is causing this.

[frozenbears]

@danomatika I don't know if this helps or just adds to the mystery, but on my machine (2013 era Macbook running High Sierra and Xcode 10) the problem goes away for the debug scheme if optimizations are turned on at level -O2 or higher.

[danomatika]

This appears to be caused by the glm used by the bindings not initializing vector values in the empty constructors which leads to memory corruption. Setting the #define GLM_FORCE_CTOR_INIT in the glm.i SWIG interface appears to be the fix.

[danomatika]

Now fixed with updated bindings in ofxLua 1.4.4.
