[issue18398] Debug Python build fails on OS X: Fatal Python error: bad ID: Allocated using API 'm', verified using API 'r'

Further testing shows that the problem is not limited to OS X 10.8 or clang: a similar debug build attempt fails on OS X 10.6 with Apple gcc-4.2.

./configure --with-pydebug CC=gcc-4.2 MACOSX_DEPLOYMENT_TARGET=10.6
make
gcc-4.2   -Wl,-stack_size,1000000  -framework CoreFoundation -o python.exe Modules/python.o libpython3.4dm.a -ldl  -framework CoreFoundation
./python.exe -E -S -m sysconfig --generate-posix-vars
Debug memory block at address p=0x100515a40: API 'm'
    232 bytes originally requested
    The 7 pad bytes at p-7 are FORBIDDENBYTE, as expected.
    The 8 pad bytes at tail=0x100515b28 are FORBIDDENBYTE, as expected.
    The block was made by call #5440 to debug malloc/realloc.
    Data at p: 2f 00 00 00 75 00 00 00 ... 6e 00 00 00 00 00 00 00
Fatal Python error: bad ID: Allocated using API 'm', verified using API 'r'
