I don't understand your request. The git repo of my vim config was the working directory where gtags was run when it crashed. It is the reproduction environment.
I can send you the partial gtags files that were generated and cause the error on incremental update, if you like, but they are large, as you can see from the file listing (GTAGS file was 353.9MB, GRTAGS was 4.3MB, GPATH was 2.1MB). Strangely, after deleting those files and running non-incremental build, it finishes with only 327KB GPATH, 16.4KB GRTAGS, and 1.1MB GTAGS. I have no idea how the files that cause the crash could have gotten so large. But only gtags created them, and it crashes with --incremental. Since it's working on newly generated database, and subsequent incremental works fine, I will just report back if it happens again. Thanks. ____ On Sun, Jul 28, 2024 at 4:43 PM Shigio YAMAGUCHI <[email protected]> wrote: > Hello, > Could you please send me a reproduction environment without > vim-related files?
