我的php应用程序崩溃了php-fpm，这导致了核心转储文件。使用MERGE INTO `s1`.`t1` `t`
USING
( Select `q`.`a1`,
`q`.`a2`
FROM (
SELECT `r`.`a1`,
`r`.`a2`,
ROW_NUMBER()
OVER ( PARTITION BY `r`.a1
ORDER BY
CAST(`r`.`a3` AS STRING) DESC
) `rank`
FROM `s2`.`t2`) q
where q.rank = 1 limit 10000
) `s`
ON ( `t`.`a1` = `s`.`a1`)
WHEN MATCHED THEN UPDATE
SET ...
WHEN NOT MATCHED THEN INSERT VALUES ..
显示以下内容：
gdb php core.2416所以我按照建议去做：
Reading symbols from /usr/bin/php...(no debugging symbols found)...done.
warning: core file may not match specified executable file.
[New Thread 2416]
Reading symbols from /lib64/ld-linux-x86-64.so.2...Reading symbols from /usr/lib/debug/lib64/ld-2.12.so.debug...done.
done.

Missing separate debuginfos, use: debuginfo-install php54w-cli-5.4.45-2.w6.x86_64
现在看：
debuginfo-install php54w-cli-5.4.45-2.w6.x86_64
如何继续执行此操作？这是php核心中的错误吗？我正在运行旧版本的php 5.4.45，由于应用程序和php扩展名依赖性，升级不可行。
