Hello, I think I have encountered the same issue. The problem occurs when emacs tries to read the secondary clipbard with the encoding iso-8859-1. You can try to reproduce the bug with : > (setf x-selection-timeout 500) > (org-get-x-clipboard 'SECONDARY) If this is the same bug, the call to `org-get-x-clipboard' will froze emacs for 500ms then return nil. After I track this down I found a quick-fix : > (setf x-selection-timeout 10) This set the timeout to 10ms instead of 0 (i.e. wait indefinitely) At the time, I ran out of patience and didn't bother to find out if the bug was specific to OpenBSD or some weird interactions between emacs and my window manager and/or X. But if you confirm the same bug it may be time to report it. Best, PS: You can usually recover from a frozen emacs by sending the SIGUSR2 signal to the emacs' process (pkill -USR2 emacs). When it receives SIGUSR2, emacs will drop into its debugger and toggle debug-on-quit (SIGUSR2 is like C-g but emacs should react to it even if the input loop is frozen). > The command I used to build the port: > > cd /usr/ports/editors/emacs > doas sh -c 'export FLAVOR=athena; export DEBUG="-g -O0 -DTRACE_SELECTION"; > make clean repackage reinstall' > > The stacktrace from the moment it hangs: > > info thre > 4 thread 424274 _thread_sys_poll () at -:3 > 3 thread 437321 _thread_sys_poll () at -:3 > * 2 thread 476142 _thread_sys_poll () at -:3 > 1 thread 131181 wait_reading_process_output (time_limit=5, nsecs=0, > read_kbd=0, do_display=false, wait_for_cell=16374659, wait_proc=0x0, > just_wait_proc=0) at process.c:5296 > (gdb) thr 4 > [Switching to thread 4 (thread 424274)]#0 _thread_sys_poll () at -:3 > 3 in - > (gdb) inf sta > #0 _thread_sys_poll () at -:3 > #1 0x00000002c6d1f45f in _libc_poll_cancel (fds=Variable "fds" is not > available. > ) > at /usr/src/lib/libc/sys/w_poll.c:27 > #2 0x000000022d883497 in g_main_context_iterate () at gmain.c:4271 > #3 0x000000022d883594 in g_main_context_iteration (context=0x20ddb0500, > may_block=The value of variable 'may_block' is distributed across several > locations, and GDB cannot access its value. > > ) at gmain.c:4033 > #4 0x00000002c7f2bb7d in g_io_module_query () > from /usr/local/lib/gio/modules/libdconfsettings.so > #5 0x000000022d8ac3fa in g_thread_proxy (data=0x259d50190) at gthread.c:784 > #6 0x0000000275642cae in _rthread_start (v=Variable "v" is not available. > ) > at /usr/src/lib/librthread/rthread.c:96 > #7 0x00000002c6d1b96b in __tfork_thread () > at /usr/src/lib/libc/arch/amd64/sys/tfork_thread.S:75 > #8 0x0000000000000000 in ??
