Hello, after lots of testing, it was discovered that the lockup problem of CPython on m68k is caused by the -fthread-jumps optimization. [1] Thus, it's therefore not necessary to build the whole interpretor with -O1, it's enough to turn that optimization off with -fno-thread-jumps. Could you just pass -fno-thread-jumps in debian/rules to CFLAGS instead of -O1? --- debian/rules.orig 2026-05-11 03:38:08.000000000 +0200 +++ debian/rules 2026-06-10 00:40:31.672179962 +0200 @@ -204,8 +204,8 @@ endif ifneq (,$(filter $(DEB_HOST_ARCH), m68k)) - OPT_CFLAGS += $(filter-out -O%,$(DPKG_CFLAGS)) -O1 - OPT_PIE_CFLAGS += $(filter-out -O%,$(DPKG_PIE_CFLAGS)) -O1 + OPT_CFLAGS += -fno-thread-jumps + OPT_PIE_CFLAGS += -fno-thread-jumps endif ifeq ($(DEB_HOST_GNU_TYPE),$(DEB_BUILD_GNU_TYPE)) Thanks, Adrian -- .''`.
