Probably a bug!

198710:
My c++ code about stl_list is complied with warning :" '__p' might be used uninitialized in this function " under the circumstance where "codeblocks-8.02mingw-setup.exe" is installed.
However,the warnings no longer exist if I install "codeblocks-8.02-setup.exe" and MinGW separately,thus I guess it's C::B's integration problem because I even tried to replace the "MinGW" folder and "mingwm10.dll" under codeblocks program directory.
Here's my code(in the attachment)

Your code is syntactically correct (though you really should be using const references as function parameters in several places). Possibly this  is a problem with the old verdion of GCC  that comes with the CB release version. If using a later version of GCC fixes the problem, as seems to be the case, I don't think you have anything to worry about.

Well,then did you notice I said "I even tried to replace the "MinGW" folder and "mingwm10.dll" under codeblocks program directory"?
I replaced the default MinGW folder and "mingwm10.dll" inside "codeblocks-8.02mingw-setup.exe" with the "correct-compile-result" MinGW folder and "mingwm10.dll",still warnings...

You said:

However,the warnings no longer exist if I install "codeblocks-8.02-setup.exe" and MinGW separately,

so I'm a bit confused as to what your problem is - are you still getting warnings or not? And which version of MinGW are you installing separately?

 

198710:
On my local machine,I installed "codeblocks-8.02mingw-setup.exe";
On my Virtual PC 2007(virtual WinXP guest),I installed "codeblocks-8.02-setup.exe" and MinGW separately,and the MinGW version is "MinGW-5.1.6.exe" from http://sourceforge.net/projects/mingw/files/;
Then I deleted the folder "C:\Program Files\CodeBlocks\MinGW" on my local machine,copied "C:\MinGW"(virtual machine) to "C:\Program Files\CodeBlocks\MinGW"(local machine),and replaced "C:\Program Files\CodeBlocks\mingwm10.dll"(local machine) with "C:\MinGW\bin\mingwm10.dll"(virtual machine) as well.
Warnings never occur on the virtual machine and never disappear on the local one.
