The backtrace is valid. Don't you think that this backtrace is more useful
than just "Segmentation fault"?

I didn't tried with patch version 9, but with the patch version 10 I get:
-----------------
$ ./python Lib/test/crashers/nasty_eq_vs_dict.py
Fatal Python error: Segmentation fault
Traceback (most recent call first):
File "Lib/test/crashers/nasty_eq_vs_dict.py", line 16 in __hash__
File "Lib/test/crashers/nasty_eq_vs_dict.py", line 40 in __fill_dict
File "Lib/test/crashers/nasty_eq_vs_dict.py", line 30 in __eq__
File "Lib/test/crashers/nasty_eq_vs_dict.py", line 47 in <module>
Segmentation fault
Erreur de segmentation
$ echo $?
139
-----------------

Patch version 9 doesn't call the previous handler. Please retry with patch
version 10 (which call the previous handler).
With the patch version 10 I get:
-----------------
$ ./python Lib/test/crashers/compiler_recursion.py
Fatal Python error: Segmentation fault
Traceback (most recent call first):
File "Lib/test/crashers/compiler_recursion.py", line 5 in <module>
Segmentation fault
Erreur de segmentation
$ echo $?
139
