Running ./emacs in src/ within gdb (invoking it with -Q), I'm getting: Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1". Program received signal SIGSEGV, Segmentation fault. build_frame_matrix_from_leaf_window (w=0x555555b8c140, frame_matrix=) at dispnew.c:2531 2531 fill_up_frame_row_with_spaces (frame_row, window_matrix->matrix_x); This is on a Linux 5.7 kernel, Debian unstable, x86-64, but I can replicate it on a raspi running 5.4 and stable. It appears to be related to -nw somehow; using that triggers the crash on the Pi (otherwise it starts up normally). On the first machine, configure options are "--with-x-toolkit=no --without-x --with-mailutils --enable-link-time-optimization". I'm sorry I can't be more detailed, but it's kind of hard to run M-x report-emacs-bug under the circumstances. I can, of course, test any patches. -- Liam Stitt stittl@cuug.ab.ca
