When using render functions from SDL2_ttf, a program compiles and runs fine in PPSSPP, but crashes on a real system. After compiling the pspdev version of SDL2_ttf, however, these functions work as intended.
For full disclosure, the functions I attempted to run were TTF_RenderText_Solid and TTF_RenderUTF8_Solid, and they were tested on a Vita running Adrenaline.
