Tim Peters added the comment:

Someone may find the new stress.valgrind.stderr interesting, but - since I've 
never used valgrind - it doesn't mean much to me.

I _expected_ you'd run the little stress program under a debug Python and 
without valgrind, since that's the only combination you've tried so far that 
showed a definite problem ("pad leading pad byte" death, or the segfault in the 
other issue you filed).

But it doesn't much matter - this is all just thrashing at random, yes?  You 
need to find a reproducible test case, and/or try different hardware.  The 
little stress program may or may not provoke an error under a debug-build 
Python, and may or may not require increasing N (to consume more RAM).

If it does provoke an error, the next thing to try would be to write a little 
program that just writes 0xfb across a massive number of bytes, and then reads 
them all to verify they're still 0xfb.  Or write one like that now, and 
preferably in C (it may matter how quickly the bytes are written - and it may 
not matter).  But at this point youj're starting to write your own 
memory-testing program.

In any case, there's really no evidence of an error in Python so far.  Yes, 
Python has _detected_ a problem in some cases.  But without a reproducible test 
case, I don't see that there's anything more we can do for you on our end - 
sorry.
