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");'
------------------------------------------------------------------------

No luck...
With the original configuration, I tried:
# LD_LIBRARY_PATH=/opt/local/lib ; export LD_LIBRARY_PATH ; php -r 'echo
iconv("UTF-8", "UTF-8", "Hello, world.\n");'
as well as:
# LD_LIBRARY_PATH=/opt/local/lib php -r 'echo iconv("UTF-8", "UTF-8",
"Hello,
world.\n");'
as well as reconfiguring with:
# ./configure --disable-iconv --with-iconv
and also tried:
# ./configure LDFLAGS=/opt/local/lib --with-iconv
and:
# ./configure LDFLAGS=/opt/local/lib --disable-iconv --with-iconv
Note: I did get a "Notice: Following unknown configure options were
used: --
disable-iconv" when trying to follow johannes advice, and
--disable-iconv isn't
listed in ./configure --help.
In ALL of the above cases when testing PHP's iconv() I got a segfault
and
checked the backtrace with gdb after each and they were all identical:

Any other ideas?

what happens when you do some thing like
LD_LIBRARY_PATH=/opt/local/lib ; export LD_LIBRARY_PATH ; php -r 'echo
iconv("UTF-8", "UTF-8", "Hello, world.\n");'

Which version of solaris are you using? My Solaris 11 express works
fine. Could you also try doing a
./configure --disable-iconv --with-iconv
build? Yor stacktrace shows
#1 0xfe8d68ab in iconv () from /lib/libc.so.1
so the libc's iconv is being used. My assumption is that another library
is using iconv from /opt/local and so the linker pulls the libs in the
wrong order so one version is used for compiling PHP the other for
running ...
