New IrrFontTool crashes on Linux

[upbaker]

This line was causing a segfault:

Code: Select all

Display* display = (Display*)Device->getVideoDriver()->getExposedVideoData().OpenGLLinux.X11Display;

Code: Select all

467		CFontTool *fc = new CFontTool(device);
(gdb) n

Program received signal SIGSEGV, Segmentation fault.

#2  0x00005555555576b5 in main () at main.cpp:467

I wasn't sure exactly what was crashing, but after changing the line too:

Code: Select all

irr::video::IVideoDriver * driver = Device->getVideoDriver()
Display* display = (Display*)driver->getExposedVideoData().OpenGLLinux.X11Display;

It works again, so I guess it was an issue with one of the objects being casted incorrectly. Is this the case for anybody else?

Could it be because of a re-compile? Try switching the line back - if it still crashes or continues to work.
Otherwise - did you change anything? Like compiling without bmp support (asking as I might have seen a similar problem once before because it couldn't load the default-font because of missing bmp support).
