Quartus 23 abort (core dump) on Linux - Quartus 23 abort (core dump) on Linux This started happening yesterday; I don't know why it's happening. Here's the output from the strace program: Edit: I have reinstalled my entire OS to isolate the problem. It did not solve the issue. Replies: Re: Quartus 23 abort (core dump) on Linux The issue was the update to fontconfig. There are a few ways to solve it. Installing fontconfig-ubuntu from the AUR, which replaces and provides fontconfig, was the way I solved it. You can also edit your pacman.conf to ignore updates to fontconfig and roll it back to the 2-15 version Note that keeping outdated packages like this on your system could cause many problems.

The issue has been found out and is described within the comments at the AUR page. It has to do with the fontconfig library.
