The code was written on top of buffers of `char[26]`, and then was changed to use `char *`, yet was still using `sizeof buf`, which became `sizeof (char *)` instead of `sizeof (char[26])`. Reported by Dagobert Michelsen. https://lists.gnu.org/r/bug-bison/2020-07/msg00023.html * src/glyphs.h, src/glyphs.c: Get rid of uses of `char *`, use only glyph_buffer_t.
