Note quite: create_default_per_dir_config() and create_server_config()
use total_modules + DYNAMIC_MODULE_LIMIT. They are the only ones that are
called before config files are parsed, and any LoadModules are picked
up. create_empty_config() is only called later, after the config files
have been parsed and total_modules is what it says, the total number of
modules you have loaded in:

The 1.2 add_module() is completely screwed up, if you're doing anything
other than a straight ClearModuleList/AddModules. It was broken when the
AddModule code was written, but that code just barely avoided tickling
the bugs. I discovered that when I wrote mod_dll for the Win32 port.

So for 1.3 I rewrote add_module() to increase total_modules when it adds
modules, so any additional config vector creation is at least large
enough (possibly too large, but I don't worry about that too much).

Xavier, try downloading 1.3a1 (or 1.3b1, which should be released
shortly), and see if things work with it. I believe they will.
