Not sure. I'm trying to type \include{../common/config.tex} and it crashes (seems not the case, though).

[sunderme]

a test case is needed

[homocomputeris]

I think I figured it out:

1. Create a file, say, main.tex
2. Add magic comment with root=main.tex
3. Rename the file to something like file.tex
4. Do not update the magic comment.
5. Try to compile: some file like /tmp/main_Sgdjk.tex will be compiled instead of file.tex.
6. Try to include something like \include{../file/text.tex}
7. TXS will likely crash

[sunderme]

clarification needed: "Rename the file to something like file.tex", how ? in terminal ?

[sunderme]

I have seen and fixed "a" crash. Can you try latest dev build / master ?

[homocomputeris]

clarification needed: "Rename the file to something like file.tex", how ? in terminal ?

In any way. You just need to have a name that differs from the magic comment in the file.

My assumptions is that when TXS puts a mismatching pseudo-root into /tmp/, \input{../config/whatever} tries to read/write from / and fails without permissions.

[homocomputeris]

Can you try latest dev build / master ?

That's a bit painful on Arch, but I'll try.

That's a bit painful on Arch, but I'll try.

how is it painful ? You can easily compile ?
