Summary: PHP built from source on Solaris gets SIGSEGV with
libiconv
Status: Feedback
Type: Bug
Package: ICONV related
Operating System: Solaris
PHP Version: 5.3.5
Block user comment: N
Private report: N
New Comment:
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");'
------------------------------------------------------------------------

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");'
