Tested on r10235 via agartest.
Simply launch agartest and press any key in the text entry box.
A full console log is attached including verbose debug output from
libagar. This was tested on Ubuntu 18.04, here are my compiler versions:

A bit of poking (in a separate session) turned up this:
(gdb) p agTextState
$1 = (AG_TextState *) 0x7ffff75dec18 <agTextStateStack+120>
(gdb) p agTextState->font
$2 = (AG_Font *) 0x0
Looks like maybe the font isn't getting initialized for some reason?
