[php-src] Issue #8064: imagettfbbox call causes Apache segfault

Issue: https://github.com/php/php-src/issues/8064 Comment Author: epsilot We checked our libraries. Indeed we have several versions of gd library but it doesn't look like reason of our issue. We see from core dump that the error occurs in _/lib64/libgd.so.103_. `Thread 1 (Thread 0x7fcdd793b880 (LWP 22238)): #0 0x00007fcdbd200ddd in gdImageStringFTEx () from /lib64/libgd.so.103 No symbol table info available.` At the same time we see that this library is provided by package _gd3php_. ``` rpm -qf /lib64/libgd.so.103 gd3php-2.3.3-4.el7.remi.x86_64 ``` Version of this package matches with GD library version from phpinfo. ``` php -i | grep 'GD library' GD library Version => 2.3.3 ``` Please correct me if my conclusions are wrong.
