Hi Gregor, others, Gregor Zattler via "Bug reports for GNU Emacs" writes: > Dear Emacs developers, building the Emacs master branch > as of commit 5f5faad249747ce5bd4b7f2968f737206c136265 > on an up-to-date debian bookworm system fails if > configured with --enable-checking=yes,glyphs > [...] > > alloc.c:3446: Emacs fatal error: assertion failed: h->index_size > 1 > make[3]: *** [Makefile:325: emacs-lisp/comp.elc] Aborted > make[3]: Leaving directory '/home/grfz/src/my-next-emacs/lisp' > make[2]: *** [Makefile:1017: bootstrap-emacs.pdmp] Error 2 > make[2]: Leaving directory '/home/grfz/src/my-next-emacs/src' > make[1]: *** [Makefile:554: src] Error 2 > make[1]: Leaving directory '/home/grfz/src/my-next-emacs' > make[1]: Entering directory '/home/grfz/src/my-next-emacs' > *** > *** "make all" failed with exit status 2. > *** > *** You could try to: > *** - run "make bootstrap", which might fix the problem > *** - run "make V=1", which displays the full commands invoked by make, > *** to further investigate the problem > *** > make[1]: *** [Makefile:418: advice-on-failure] Error 2 > make[1]: Leaving directory '/home/grfz/src/my-next-emacs' > make: *** [Makefile:374: all] Error 2 I ran into what looks like the same error when building but could not reliably reproduce it. However, I *am* able to reproduce something possibly related. Because I'm not sure, I replied to your original post rather than down thread (so as not to cause an unnecessary ruckus). Unfortunately, to run the test shown in the attached log you need a file that's not in the Emacs tree. It can be generated with 1. $ mkdir test/lisp/erc/resources/fill/snapshots/.graphic 2. $ ERC_TESTS_SNAPSHOT_SAVE=erc-fill-wrap--merge-action \ make -C test \ TEST_INTERACTIVE=yes \ SELECTOR=erc-fill-wrap--merge-action \ lisp/erc/erc-fill-tests.log && rm test/lisp/erc/erc-fill-tests.log && stat test/lisp/erc/resources/fill/snapshots/.graphic/merge-wrap-01.eld The current directory in the logged session is ./test, and the invoking command appears on the first line of the log. Thanks.
