Summary: PHP built with libconv crashes after iconv() is
called
Status: Open
Type: Bug
Package: Reproducible crash
Operating System: FreeBSD 10.3
PHP Version: 7.0.6
Block user comment: N
Private report: N
New Comment:
The documentation from ./configure is misleading.
# ./configure --help | grep -i iconv
--without-iconv=DIR Exclude iconv support
--with-iconv-dir=DIR XMLRPC-EPI: iconv dir for XMLRPC-EPI
However --with-iconv-dir seems to be not respected, and thus PHP ends up using the BSD version of
libiconv, which causes the bus error.
When passing --with-iconv=/usr/local you get the correctly installed from ports libiconv from
/usr/local
Maybe add a failure case in ./configure if the library included is the BSD version? __bsd_iconv that
cmb at php dot net mentioned is a likely culprit.

I am experiencing this on FreeBSD 12.0-RELEASE-p3 compiling PHP 7.3.5 from source using
--with-iconv-dir=/usr/local
I've installed libiconv from ports but FreeBSD after 10-CURRENT on 2013-08-13 have iconv
installed as part of the OS. It may be that the configure script, regardless of the value of DIR
(/usr vs /usr/local) may pick up the port rather than the native library in
/usr/lib/i18n/libiconv_std.so.4 vs /usr/local/lib/libiconv.so.2.5.1
I've tried DIR as both /usr and /usr/local without luck, still get the bus error. I'm
going to dig a bit more to see if there is a lingering path issue in my environment, another
./configure var that will fix this on FreeBSD, or if another change is required.
It is still an issue when compiling PHP 7.3 from source on FreeBSD. Along with mysqli and mariadb,
but that's another bug. :-)

This looks wrong.

I've compiled phpXX-iconv with
CONFIGURE_ARGS+=--with-iconv=/usr/local
Now it works
