I got a segmentation fault after viewing a PDF file. I'm not sure
what I did. It could have occurred immediately (like in bug 1032609)
or after I typed 'a'.

Information from gdb:

and I've attached the backtrace and the PDF file (similar to
https://www.open-std.org/jtc1/sc22/wg14/www/docs/n3232.pdf but
recompressed).

Closing since this is a bug against an old zathura version
(and libraries have changed too), and I have not got a
segmentation fault in "normal use" since then.
