A numerical value argument of the os.putenv() call causes my python3.5 to crash with SIGSEGV, for example:Python 3.5.0+ (default, Oct 11 2015, 09:05:38) [GCC 5.2.1 20151010] on linuxType "help", "copyright", "credits" or "license" for more information.>>> import os>>> os.putenv('AAA', 1)Segmentation fault (core dumped)While numerical 1 (one) is not a valid argument for the function which expects a string as value, it shouldn't crash but rather throw an exception. This seems to be the behaviour in python3.4:Python 3.4.3 (default, Oct 14 2015, 20:28:29) [GCC 4.8.4] on linuxType "help", "copyright", "credits" or "license" for more information.>>> import os>>> os.putenv('AAA', 1)Traceback (most recent call last):  File "<stdin>", line 1, in <module>TypeError: Can't convert 'int' object to str implicitly>>>I can provide a strace/ltrace/core dump but it's huge and I'm not sure if it's necessary taking into account that this issue is trivial to reproduce.
