I have a speculation to share. In the project that produced SIGSEGV, I was using lsp-mode. It asks if I want to "watch files" every time I open a project. I added really high threshold for the number of allowed watched files in .dir-locals. Shortly after I encountered the SIGSEGV for the first time. I now changed it back to not watching the files, and I am not encountering the problem anymore. In the Bug#39164 upstream: https://debbugs.gnu.org/cgi/bugreport.cgi?bug=39164, they also mention lsp-mode. I am not sure if that helps but I believe, enabling file watching in lsp-mode on a big project consumes enough memory to make the bug more likely to reoccur. BR, Tomasz Kowal
