Thanks for the help.
We got it working with:
./configure --with-iconv=/opt/local
It seems like it could be really helpful for people if there was anyway for the
compiler to test for this case so that if people just specify "--with-iconv"
they
don't get hard-to-debug seg faults.

As Johannes and the core dump output show this has nothing to do with php core.
this is a compilation issue mainly due to the way your environment is set up.
this is what i did
- unset LD_LIBRARY_PATH
- installed libiconv in /opt/local
- compiled php as ./configure --disable-all --with-iconv=/opt/local
- ldd sapi/cli/php | grep iconv and verify that PHP is depending on
/opt/local/lib
- ./sapi/cli/php -r 'echo iconv("UTF-8", "UTF-8", "Hello, world.\n");'
and got the expected results..
note: i did use the OS provided gcc for my compilation needs.
pl. note that i see that you have compiled and installed other dependent
libraries at /opt/local as well. you might want to ensure that when you
compiled those - they all depend on /opt/local/lib as well. it is not a good
idea to mix between OS provided iconv libraries vs what you compiled.
i would like to close this bug as not a valid bug if others don't have any
issue.

I meant to write --disable-all, sorry for the mistake. Could you try
./configure --disable-all --with-iconv && make && ./sapi/cli/php -r 'echo
iconv("UTF-8", "UTF-8", "Hello, world.\n");'
