Trying to compile 3.8.0b4 on an raspberry pi 3B+ and 4 running:

pi@pi4b:~/Downloads/Python-3.8.0b4 $ uname -a
Linux pi4b 4.19.66-v7l+ #1253 SMP Thu Aug 15 12:02:08 BST 2019 armv7l GNU/Linux

Using arguments:

./configure --disable-shared --enable-optimizations --enable-loadable-sqlite-extensions --enable-ipv6 --enable-big-digits --with-lto --with-doc-strings --with-ensurepip --with-openssl=/usr

fails compilation at the linking stage with the errors:

For hundreds of lines.

Removing the --enable-optimizations flag allows it compile and link.

Could you provide the output of 

  gcc --version

and

  ld --version

pi@pi4b:~ $ gcc --version
gcc (Raspbian 8.3.0-6+rpi1) 8.3.0

pi@pi4b:~ $ ld --version
GNU ld (GNU Binutils for Raspbian) 2.31.1

I'll be more than happy to buy you an RPi to do testing on.

Hmm, I think this might be the following gcc/binutils bug: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=84847
https://sourceware.org/bugzilla/show_bug.cgi?id=20882

This might be a bit of a pain but could you try updating binutils and see if the problem persists.

I updated binutils:

pi@pi4b:~/Downloads/Python-3.8.0b4 $ ld --version
GNU ld (GNU Binutils) 2.32

Same problem.
