The occurrence of the problem:
After I updated my php7.2, I executed the php composer self-update command and a Segmentation fault error occurred. Through gdb debugging, I found that the problem appeared on libssl.so. I looked at ldd .../74/bin/php and it appeared Two libssl.so, the problem is here, my final solution is to remove the absolute path of --with-curl and --with-openssl in the official php.sh script, and comment out if ["${ withOpenssl}" ];then...fi to ensure that php8 can compile and run
gdb:
Core was generated by `php composer self-update -vvv'.
Program terminated with signal SIGSEGV, Segmentation fault.
