Wow, you are putting quite a lot of energy into this :-)

Looks allright. If thttpd starts up, it is very unlikely
that you did something wrong during building it.

We are dereferencing a pointer in line 189, but that pointer
seems to be valid. So, I don't see any reason why it would
segfault at that point.
As you are seeing this problem on multiple Linux
installations, I'd recommened to use the install_ircg.sh
script from
http://schumann.cx/ircg/install_ircg.sh
and set CFLAGS in line 19 to "-g". Also make sure that you
don't have any old header files/libraries hanging around.
