I build (B)LFS with the intent of being able to install it on any "compatible" system, so I've generally been cross-compiling all my builds on my Bloomfield i7-940 with CFLAGS="-march=x86-64 -mtune=generic", with a few exceptions: gmp, etc., so I can put them on, say, a Conroe Core-2 Duo. > > List, I didn't realise that the same problem was already discussed on > this mailing list.

Yep, as Filip mentioned, we've seen this problem recently. I've filed a bug report with the libffi developers and will let the LFS list know what they say.

Mike I didn't alter any optimization flags during the compilation process. With your suggestion for gdb, I get the following result: (gdb) run -E -m ensurepip Starting program: /usr/lfs/sources/untarred/Python-3.6.4/python -E -m ensurepip [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib/libthread_db.so.1". Program received signal SIGILL, Illegal instruction. 0x73033ce4 in ffi_closure_alloc () from /usr/lib/libffi.so.6 (gdb) display/i $pc 1: x/i $pc => 0x73033ce4 : vmovq %r13,%xmm3 (gdb) Apparently, the problem lies with ffi. I will try to recompile that.

[lfs-support] make install of Python 3 causes: 3273 Illegal instruction
I am trying to make Python 3.64 in the course of creating LFS 8.2 (http://www.linuxfromscratch.org/lfs/view/stable/chapter06/Python.html) Both the ./configure and make step seem to run OK. However, executing "make install" causes: /bin/sh: line 7: 3273 Illegal instruction (core dumped) LD_LIBRARY_PATH=/usr/lfs/sources/untarred/Python-3.6.4 ./python -E -m ensurepip $ensurepip --root=/ make: *** [Makefile:1099: install] Error 132 Within the chroot environment and the build directory, I can execute the freshly built python ok: ./python ./python -V What's causing the problem seems to be the ensurepip module: ./python -E -m ensurepip I am unable to even think of a cause of this behaviour and any help on that is appreciated.
