[tex-live] xetex segfault in "TeX Live 2019/dev/Debian"?

[Ulrike Fischer]

There seem to be a source for "TeX Live 2019/dev/Debian" somewhere
and one user on ubuntu 16.04. reported in the comments a segfault
for xelatex:

https://tex.stackexchange.com/questions/460247/xelatex-doesnt-work-in-texstudio

This is XeTeX, Version 3.14159265-2.6-0.99999 (TeX Live
2019/dev/Debian) (preloaded format=xelatex) restricted \write18

(while the binaries looks ahead of their time, latex and babel are
not up-to-date).

Hi Ulrike,

I read through the issue there, and it seems that
it works on the terminal
but
breaks in texworks

I can only imagine that there is a difference in invocation. I have
tried several documents on the command line and all of them worked, so I
am not really sure what texworks is doing.

Hi all,

if this is the case, it can also be a matter of different environment
setting and/or different PATH for the termina, and GUI. This is probably
the most frequent reason of such problems in Linux.

I'm not sure. In the comments it sounds as if it breaks also on the
terminal, but not for every file. Some unknown file seemed to work,
but with sample2e it broke: "when i type the command: xelatex
sample.tex in terminal, ... "

But if he really mixed binaries from different version than probably
nothing can be done anyway.

Btw: The segfault is at the place where on windows I would expect
the recreation of the font cache (if xetex detects new fonts).

Mumumu, not very helpful without an actual test case.

Yes, that is what I expect.

There is another item, that was fixed like 2 days after the first
release by uploading a new version of texlive-bin: luatex 1.09
from current svn is just borked wrt to context (or the other way round,
hard to say, anyway, luatex breaks backwards compatibility from
1.07 to 1.09, which is IMNSHO a really stupid thing). I uploaded
a new version of texlive-binaries that reverts to 1.07 of luatex,
so it *might* be that there something involved with luatex, but
since it is a *xetex* issue, that sounds more like a stupid theory than
reality.

Can you tell me in which way it broked compatibility?

(miktex updated to luatex 1.09, and it will be in the next texlive,
so any problem should better be handled as soon as possible ...)

At least this is what I see.

I reported it to Hans, Taco, Mojca, but never got an answer.

Ah. context. Yes, context and luatex are like the biber/biblatex
combo: When you update one side you should update the other too.

Well, I expected that this does not happen on updates from
1.07 to 1.09
, but seemingly context/luatex developers have a different attitude
towards software engineering than me.
