[已解决]xdebug+phpStrom跳转报错导致闪退问题

解决方法：

phpStorm设置取消 _toString:

问题描述：

调试index.php的时候正常，但是跳转到b.php里的断点以后：断点闪退，并返回502

php-fpm报错，log：

 WARNING: [pool www] child 13746 exited on signal 11 (SIGSEGV) after 148.756432 seconds from start

nginx返回502，log:

[error] 12950#12950: *10 recv() failed (104: Connection reset by peer) while reading response header from upstream, client

调试细节：

#strace -f -F -s1000 -t -T `ps aux | grep -E 'php' | awk '{print "-p" $2}' | xargs`
#tail /var/log/messages

log：
