New submission from Michael Felt <aixto...@felt.demon.nl>:
Successfully built and packaged the Python-3.9.0 distribution tar archive
without modification - as 32-bit.
Repeating the same process with the following environment change:
# export OBJECT_MODE=64
fails with a segmentation fault by the "first-phase" python executable:
```
../src/py39-3.9.0/Modules/makexp_aix Modules/python.exp "."
libpython3.9.a
xlc_r -Wl,-bE:Modules/python.exp -lld -o python Programs/python.o
libpython3.9.a -lintl -ldl -lm -lm
./python -E -S -m sysconfig --generate-posix-vars ; if test $? -ne 0 ;
then echo "generate-posix-vars failed" ; rm -f ./pybuilddir.txt ; exit 1 ;
fi
/bin/sh: 6291700 Segmentation fault(coredump)
make: 1254-004 The error code from the last command is 139.
Stop.
root@x066:[/data/prj/python/py39-3.9.0]./python -E -S -m sysconfig
--generate-posix-vars
Segmentation fault(coredump)
root@x066:[/data/prj/python/py39-3.9.0]./python
Segmentation fault(coredump)
```
Will try to duplicate in a second environment.
