It seems to have eliminated the "reslist_cleanup: Assertion
`rl->ntotal == 0' failed" and "Aborted (6)" errors, which was the
primary goal.
Hopefully the other "corrupted size vs. prev_size" and "Segmentation
fault (11)" errors were related but it does not seem to be the case..

I can't tell this from the few pieces of information available so far.

Since httpd is now crashing with "Segmentation fault" (only), there is
a way to get a coredump file generated for further analysis, you need
to add this to your main/base httpd configuration:
CoreDumpDirectory /tmp
After each crash there should be a "/tmp/core" (or "/tmp/core.[pid]")
file which can be analysed with the gdb debugger, by using these
commands:
$ gdb /usr/sbin/httpd /tmp/core[.pid]
[and once in gdb with the "(gdb)" prompt]
(gdb) thread apply all bt
Please paste the result here.
Regards;
Yann.
