Postgresql initdb - 分段错误（核心已转储）

Question

我对pgsql源代码做了一些修改，比如添加了一个新的系统目录。然后我想使用 initdb -D PG_DATA_PATH 初始化数据库。但是却遇到了这个问题：

The files belonging to this database system will be owned by user "pguser".
This user must also own the server process.

The database cluster will be initialized with locale "en_US.UTF-8".
The default database encoding has accordingly been set to "UTF8".
The default text search configuration will be set to "english".

Data page checksums are disabled.

creating directory /home/pguser/Desktop/postgres/data ... ok
creating subdirectories ... ok
selecting dynamic shared memory implementation ... posix
selecting default max_connections ... 100
selecting default shared_buffers ... 128MB
selecting default time zone ... America/Los_Angeles
creating configuration files ... ok
running bootstrap script ... ok
performing post-bootstrap initialization ... Segmentation fault (core dumped)
child process exited with exit code 139
initdb: removing data directory "/home/pguser/Desktop/postgres/data"

当我执行 make 和 make install 时，有 NO 个错误或警告。另外，我使用 gdb 回溯了 initdb 的执行：

这个故障的潜在原因是什么？？？？ SIGPIPE信号？？？希望有人能帮助我！！！谢谢。

您有来自错误进程的核心转储。

initdb 以独立模式启动 PostgreSQL 服务器并将目录内容通过管道传输给它。现在您正在编写的数据中的某些内容是错误的，并且独立的后端退出。然后 initdb 如果它写入管道并崩溃，则会得到一个 SIGPIPE。

您想调试 PostgreSQL 服务器，而不是 initdb。
