xdvipdfmx segfault

[Vít Starý Novotný]

Dear all,

I can add another test case for the segfault.

Since at least two days ago, the Markdown package [has failed to compile
XeLaTeX example document][1] with TeX Live pretest due to a segmentation
fault with AMD64 binaries for Linux:


- [Compilation logs from 2024-02-28][4] (success)

- [Compilation logs from 2024-03-03][2] (failure)

- [Compilation logs from 2024-03-05][3] (failure)

I was able to create an MWE that reproduces the issue with current TeX Live
pretest:


```

$ xelatex example

This is XeTeX, Version 3.141592653-2.6-0.999996 (TeX Live 2024) (preloaded
format=xelatex)

\write18 enabled.

entering extended mode

(./latex-xetex.tex

LaTeX2e <2023-11-01> patch level 1

L3 programming layer <2024-02-20>

(./example.aux) )

Segmentation fault (core dumped)

(see the transcript file for additional information)

Error 35584 (driver return code) generating output;

```


You will find an archive with the MWE attached.
