Fix known issues in texlive - luatex and (x)dvipdfmx problems

[Douglas R. Reno]

Ken messaged me privately about some known issues in Texlive. Upon some research, I have found that they are (from ​https://www.tug.org/texlive/bugs.html):

• In the original release, LuaTeX did not typeset integrals correctly. This was fixed in LuaTeX development id 7673.
• In the original release, (x)dvipdfmx crashed on certain PDF inclusions. This was fixed in dvipdfmx version 20250410. Also, font subset tags are now reproducible.

We'll need to make a patch based on the following commits to fix this:

• ​https://git.texlive.info/texlive/commit/?h=tags/texlive-2025.2&id=d87a543ac272a1cfaa4a26fedb5d7bfb1727161b
• ​https://git.texlive.info/texlive/commit/?h=tags/texlive-2025.2&id=9124a48df9796345f8cbab3ae209d3aff1c0f8b4
• ​https://git.texlive.info/texlive/commit/?h=tags/texlive-2025.2&id=d01f1eb715247b85128c57c21249122e1c619fa5
• ​https://git.texlive.info/texlive/commit/?h=branch2025&id=7fb812ad3d78b70c4f2a02a89cd8f983a9d598de

I'll also subscribe to the tl-distro mailing list now to catch further issues that come up

Sorry for hijacking the thread but does anyone in chance knows how they adapt for gcc-15?

Replying to Xi Ruoyao:

No problem at all, it's a good time to bring it up! Unfortunately it looks like they suggested to other distros to use the std=gnu17 flag. There's a thread that starts here: ​https://tug.org/pipermail/tldistro/2025q1/000519.html

I also added patches for another new known issue:

"In the original release, pdftex output overlapping text with ptmr8r and other fonts. This was fixed in pdfTeX version 1.40.28; binaries were updated around May 18, 2025."
