Python test error

[Kugan Vivekanandarajah]

Hi Mathias,

I am not able to reproduce error in
https://objectstorage.prodstack4-5.canonical.com/v1/AUTH_77e2ada1e7a84929a74ba3b87153c0ac/autopkgtest-cosmic/cosmic/arm64/p/python2.7/20180901_084242_93a10@/log.gz

Do you have any instructions for reproducing it locally.

This is what I have done:

Downloaded https://www.python.org/ftp/python/2.7.4/Python-2.7.4.tgz
Applied following patch to build for aarch64:

}

ffi_sources += ffi_platforms['@TARGET@']


./configure
Also tried ./configure --enable-pydebug and --disable-optimization
Also tried changing to -O0 manually in the make file

make
./python Lib/test/regrtest.py -v test_ctypes

Used gcc version 8.2.1 20180907 (GCC)

Results are OK.

Thanks,
Kugan
