1) You understand that Hardening-Patch is not Suhosin-Patch, do you?
2) Maybe you should also search for: Have Debian, then use a clean PHP not a broken Debian build
Bug 3 -> is not a bug in Suhosin, it is the fact that the suhosin.executor.max_depth function was not set correctly. Reading the documentation helps: http://www.hardened-php.net/suhosin/configuration.html#suhosin.executor.max_depth
Bug 4 -> the guy is actually writing inside the bug report that the problem occurs with and without Suhosin
5) You can just start PHP with the environment variable SUHOSIN_MM_USE_CANARY_PROTECTION=0 and can use valgrind.
So basically all points you bring up are no issues.
