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?
