Description
We tried to use tcmalloc (tcmalloc_minimal) from gperftools v2.10 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).
