Bug report
I apology that this is really not a bug report of MiKTeX,
but a report on how MiKTeX is affected by Windows 10 ver. 1709 (OS build 16299.98).
I am asking for help.
I have developed a Chinese TeX system called cwTeX:
http://homepage.ntu.edu.tw/~ntut019/cwtex/cwtex.html
The system is a preprocessor, built on MiKTeX, plus some Chinese fonts.
It has been used to typeset many textbooks and papers in Taiwan.
A mwe is provided in the following.
The line before the last one contains 7 Chinese characters,
coming from 5 Chinese fonts (each contains 256 characters).
To typeset this file, one has to run the cwtex preprocessor first,
and then run pdflatex (or latex).
Before Windows 10 ver. 1709 (Oct. 2017), there is no problem
running this file. Win 7 and 8 are fine. So are old versions of MiKTeX.
However, the most recent update of Windows 10 (ver. 1709) created an error,
with the following message:
2017-12-09 21:58:48,734+0800 FATAL pdflatex - Line: 477
2017-12-09 22:03:01,455+0800 FATAL pdflatex - No space left on device
2017-12-09 22:03:01,455+0800 FATAL pdflatex - Info:
2017-12-09 22:03:01,455+0800 FATAL pdflatex - Source: libraries\miktex\texandfriends\include\miktex\c4p\C4P.h
Now if I deleted one or two Chinese characters in the mwe, it will run fine.
Or if I change \fontsize{120}{40pt} to \fontsize{100}{40pt},
it will also run fine.
I have tried this mwe on several computers, with different hardware,
and only one computer (8gb RAM) can avoid this problem.
It does not seem to be related to the amount of RAM,
because one computer with 16gb RAM has problem.
All the computers are installed with the most recent version of MiKTeX.
Before Microsoft fixes the issue in the future, I wonder if anything can be
done or tried, say adding options when running pdflatex, to fix the problem (maybe temporarily)?
If needed, I can send the fonts needed, or the whole system can be downloaded
form the cwTeX webpage above.
Thanks!
