相同的代码在VC6里面没问题，VS2013就编译不过


错误提示：

错误 1 error C2146: 语法错误: 缺少“;”(在标识符“pOutBuffer”的前面) d:\源代码\84 dewav_tool_system\source\dewav_tool_system_v1.0.0\toolmanagement\toolmanagementview.cpp 396 1 ToolManagement
2 IntelliSense: 应输入“;”

pOutBuffer创建的是一个数组，释放时应该用delete [] pOutBuffer, 另外你这个pOutBuffer指针还做了计算，恐怕直接释放也会出错。 这代码能在VC6下正确编译的话也是神了

你这里delete不会崩溃吗？你上面的都有修改了pOutBuffer指针的本身的值了。

不是运算不运算的问题，VS2013中是直接提示语法错误，我就很纳闷。

提示是 396行 delete pOutBuffer; //这里编译不过， 这句是 122 行 ？

在vc6下也会leak memory

[encoderlee]

new出来后保存原指针，delete的时候要用原指针来delete
