It seems like the failure comes from "env = dict(PYTHONPATH=os.pathsep.join(sys.path))" of Lib/test/test_embed.py. The code from test_pre_initialization_api() works properly. The fix seems easy.

To reproduce the bug:

./configure --with-pydebug --enabled-shared
make clean
make
LD_LIBRARY_PATH=$PWD ./python -m test -v test_embed
