I have also tried without native comp, and getting a similar crash: ``` Thread 1 "emacs" hit Breakpoint 1, 0x00005555555992da in terminate_due_to_signal () (gdb) bt full #0 0x00005555555992da in terminate_due_to_signal () #1 0x0000555555599b21 in emacs_fopen.cold () #2 0x000055555559a439 in read_minibuf_unwind.cold () #3 0x000055555574c43b in Ffuncall () #4 0x000055555579a59e in exec_byte_code () #5 0x000055555574c362 in Ffuncall () #6 0x000055555579a59e in exec_byte_code () #7 0x0000555555751109 in funcall_lambda () #8 0x000055555574c362 in Ffuncall () #9 0x0000555555750142 in Frun_hooks () #10 0x000055555574c43b in Ffuncall () #11 0x000055555574c4e5 in call1 () #12 0x00005555556d7df1 in Fget_buffer_create.part.0 () #13 0x00005555556ec52c in get_minibuffer () #14 0x00005555556ec77b in read_minibuf () #15 0x00005555556ed83d in Fread_from_minibuffer () #16 0x000055555574e2b2 in funcall_subr () #17 0x000055555574c43b in Ffuncall () #18 0x000055555579a59e in exec_byte_code () #19 0x000055555574c362 in Ffuncall () #20 0x000055555579a59e in exec_byte_code () #21 0x000055555574c362 in Ffuncall () #22 0x000055555579a59e in exec_byte_code () #23 0x000055555574c362 in Ffuncall () #24 0x0000555555748695 in Ffuncall_interactively () #25 0x000055555574c43b in Ffuncall () #26 0x000055555574ec80 in Fapply () #27 0x0000555555749e7a in Fcall_interactively () #28 0x000055555574c43b in Ffuncall () #29 0x000055555579a59e in exec_byte_code () #30 0x000055555574c362 in Ffuncall () #31 0x000055555574c4e5 in call1 () #32 0x00005555556c2fe9 in command_loop_1 () #33 0x000055555574b3ff in internal_condition_case () #34 0x00005555556b0544 in command_loop_2 () #35 0x000055555574e0eb in internal_catch () #36 0x00005555556b04e3 in command_loop () #37 0x00005555556b70da in recursive_edit_1 () #38 0x00005555556b7415 in Frecursive_edit () #39 0x00005555555a3dfe in main () 'backtrace_top' has unknown return type; cast the call to its declared return type ``` This seems to isolate the issue to `read_minibuf_unwind`, which is part of the changeset of the commit I bisected to.
