Interesting.

Could you post the result of:

$ valgrind --tool=memcheck --suppressions=Misc/valgrind-python.supp Modules/_testembed

after having un-commented the ADDRESS_IN_RANGE suppressions from Misc/valgrind-python.supp?

What compiler version are you using?
Could you try compiling with -O0, then with -fstack-protector-all?
