[php-src] Issue #11564: crash due to invalid pointer in mysqli with tcmalloc

Issue: https://github.com/php/php-src/issues/11564 Author: sephiroth-j ### Description We tried to use tcmalloc (tcmalloc_minimal) from [gperftools v2.10](https://github.com/gperftools/gperftools) together with PHP. Unfortunately PHP-FPM crashes right at the beginning in mysqli.so. We tried both variants: a) adding LD_PRELOAD=/opt/lamprt/lib/libtcmalloc_minimal.so and b) adding libtcmalloc_minimal at compile time with -ltcmalloc_minimal without LD_PRELOAD. Both variants cause a crash. Below is the stack trace of variant a). ``` Jun 30 09:59:58 demo systemd-coredump[112399]: Process 112397 (php-fpm) of user 0 dumped core.
