I’m using sdl_ttf inside sdl component for Gambas
http://gambas.sourceforge.net
The code works great for pfa and pfb fonts, but fail with ttf font ! (p.e.
timersi.ttf from corefonts), i can get ascent,descent but failed (segfault)
when i try to get the size with TTF_SizeUTF8 or print text.
sdl-1.2.8, sdl_ttf-2.0.7 and freetype-2.1.5 under gentoo/x86–
