Current font caching algorithm contains a use after free error. A font removed from `frc` might be still listed in `wx.specbuf`. It will lead to a crash inside `XftDrawGlyphFontSpec()`. Steps to reproduce: $ st -f 'Misc Tamsyn:scalable=false' $ curl https://www.cl.cam.ac.uk/~mgk25/ucs/examples/UTF-8-demo.txt Of course, result depends on fonts installed on a system and fontconfig. In my case, I'm getting consistent segfaults with different fonts. I replaced a fixed array with a simple unbounded buffer with a constant growth rate. Cache starts with a capacity of 0, gets increments by 16, and never shrinks. On my machine after `cat UTF-8-demo.txt` buffer reaches a capacity of 192. During casual use capacity stays at 0. |

Afterwards enter the following command to build and install st (if necessary as root): make clean install Running st ---------- If you did not install st with make clean install, you must compile the st terminfo entry with the following command: tic -sx st.info See the man page for additional details.
