像上面这样(NtWaitForSingleObject)的thread还是几百个，都是重复的内容，删除了

看错误提示好像是在调用freemem时发生了错误，但是调用freemem里没有我的代码（基本上有行号信息的是在编译时有.pas文件的），难道是indy9.18版有bug？

三天两头的崩溃，我快疯掉了！

[myy]

indy9.18版 ? bug 多多啊...

[GARNETT2183]

这样看来这个没多少人会懂...~+~

[dabaicai]

三天两头的崩溃???? 那不是不好检查错误了
也不一定就是indy9 的bug问题

[getit911]

最好把代码贴出来。

[peihexian]

哪位高人帮忙啊？
