Description PoroCYon 2017-04-14 01:08:50 UTC 
Created attachment 2720 [details]
The font file causing the mess.

In version 2.0.14*, calling `TTF_OpenFont` with a font with exotic glyphs (added as an attachment) causes the process to allocate more and more memory, until it runs out.

The font can be seen here: http://zanxi.jbo.run/ (does not cause my browser to run out of memory, however.)

*: Arch package
Comment 1 Sam Lantinga 2017-09-10 07:25:55 UTC 
Tested with the latest SDL_ttf at http://hg.libsdl.org/SDL_ttf and FreeType 2.8, with no problems.

I suspect this was a bug in the version of FreeType shipped with SDL_ttf and this has been fixed.
