Well, yeah it simply didn't segfault anymore. From running make test
it seemed that many
tests failed so I didn't bother running it through.

Okay, I applied this patch to the 2.0 Version. Apache no longer
segfaults but 201 out of 229 test scripts fail:
Failed 201/229 test scripts, 12.23% okay. 377/684 subtests failed, 44.88% okay.
Judging from the error_log it's because the apache-childs segfault. I
have attached with gdb to the running test apache, and when accessing
http://localhost:8531/TestUser__rewrite_real the child segfaults:
Program received signal SIGSEGV, Segmentation fault.

If you need anything else just tell me. If a verbose test-report is
needed just tell me which test.
Thank you very much for your help and kind regards
