GFX gui segfaults on ubuntu 14.04, nvidia-346

[tingelst]

The examples with a call to gui() in setup() segfaults on ubuntu 14.04 with nvidia-346 driver. I have debugged it down to the 3rd call to OnDraw() in gfx_control.h.

Tested with xFabrikChain.cpp

Seems like a problem with mWindowEventHandlers

The examples compile and run when the call to gui is commented out. Examples in glv also compiles and run.

There was an issue which made me realize I am not building glv in the buildAll.sh script. I don't think this is causing the bug, but it theoretically could be, if a different version of glv is installed on the machine. to be sure the glv library is built with the same headers that are referenced run

cd versor
make -C ext/glv

I think you mentioned earlier though that glv is running fine from within ext/glv so it must in gfx/util/gfx_gui.h where the gui struct is defined or gfx_control.h as you mentioned.

I'm having the same problem. "make -C ext/glv " is in buildAll.sh

probably of no help, but here's what valgrind had to say when I ran "valgrind ./test_units":

my laptop using the noveua driver builds no problem however.
