[New-bugs-announce] [issue38204] Cannot compile on RPi with optimizations

[Thomas Knox]

New submission from Thomas Knox <tknox at mac.com>:

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

pi at 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.
