我使用PostgreSQL在FreeBSD 10.2上编译了CLang 3.7。问题是我无法使用LLDB 3.7附加到后端进程：
[eax@freebsd102 ~]$ ps wuax | grep postgres
eax 29177 0.0 2.0 169592 20888 - Is 6:11PM 0:00.00 postgres: checkpointer process (postgres)

eax 29196 0.0 0.2 18824 2340 1 S+ 6:15PM 0:00.00 grep postgres
[eax@freebsd102 ~]$ lldb -p 29192
(lldb) process attach --pid 29192
error: attach failed: unable to find executable for 'postgres: eax eax [local] idle'
(lldb) q
与此同时，一切都按照预期的方式运行，其中包含＆＃34;常规名称＆＃34;：
[eax@freebsd102 ~]$ lldb -p 29192
(lldb) process attach --pid 29192
error: attach failed: unable to find executable for 'postgres: eax eax [local] idle'
(lldb) q
[eax@freebsd102 ~]$ lldb -p 29083
(lldb) process attach --pid 29083
Process 29083 stopped
Executable module set to "/usr/home/eax/postgresql-install/bin/postgres".
Architecture set to: x86_64-unknown-freebsd10.2-unknown.

有任何想法如何解决这个问题？
UPD：gdb / gcc中没有这样的问题。
