--- Comment #5 from ohaiziejohwahkeezuoz at xff dot cz --- Reproducing this might be somewhat complicated, because harfbuzz has some dependencies, which would also needed to be built. But I have captured the failing command, and can run gdb on it interactively after segault, so if you have any suggestions on what to look for, or how to extract more detail other than the backtrace I've provided, I can do some debugging on my side. It's failing at the final linking step (probably during the load/parsing of lto object files from disk), where all the many object files are processed by the LTO, so I can't provide the reduced testcase. I'll check if harfbuzz 2.3.1 builds with gcc 8.2.0 (2.3.0 did, so that might help in reducing the search space).
