#159 Xelatex generate bad pdf for certain Chinese fonts

[Anonymous]

I compile the xetextest.tex with texlive 2018 and texlive 2019. The former generated a correct pdf file, however the later generated a corrupted pdf.

As shown in xetextest-2019.log PDF output driver (dvipdfmx) failed to process the input for some reasons.

Error 139 (driver return code) generating output;
file xetextest.pdf may not be valid.

It is not possible to verify the problem further since the "corrupted" pdf is not provided and the problem can't be reproduced since your installation is not clear at all.
