Fixed by: https://git.ghostscript.com/?p=mupdf.git;h=fa1936405b6a84e5c9bb440912c23d532772f958
Possibly introduced with: https://git.ghostscript.com/?p=mupdf.git;h=e767bd783d91ae88cd79da19e79afb2c36bcf32a (1.7-rc1)
Although the e767bd783d91ae88cd79da19e79afb2c36bcf32a introduced the solid xrefs,
that part of the code went trough several iterations before it settled down, and
thus the issue could possibly be presend already before. The code in 1.5-1 looks
quite similar, although the reproducer does not lead to a heap-use-after-free in
the 1.5-1 case.
