我正在调试内存泄漏的程序。启用“check -memuse”时出现以下错误：
Write to unallocated (wua) on thread 1:
Attempting to write 8 bytes at address 0xffffffff79f001d0
t@1 (l@1) stopped in _private_pthread_atfork at 0xffffffff5bd4ce28
当我发出 Where 命令时：
current thread: t@1
=>[1] _private_pthread_atfork(0xffffffff64d565ac, 0xffffffff64d5660c, 0xffffffff64d565dc, 0xffffffff79f001c0, 0xffffffff64eb6a50, 0xffffffff5bf4a360), at 0xffffffff5bd4ce28

[6] _rt_boot(0x0, 0x0, 0x0, 0x0, 0x0, 0x0), at 0xffffffff7f608028
我可以追溯到代码中发生此错误的位置吗？您能否提供一些帮助以追溯到源头？

这是一个 proC 过程。在 10g 上编译时，它工作正常。提供的二进制文件正在加载 Oracle 10g 库。但是当用 11g 编译时会出现错误。在调试过程中，我在以下代码中发现了 10g 内存泄漏：
EXEC SQL CONNECT :Userid;
oraca.orastxtf = ORASTFANY;

在 11g 调试相同代码期间，我得到以下内存泄漏：

任何人都可以有这样的问题吗？
