I use `x64 msvc v19.24` version, which gives `@"??0?$AutoParmTemplate@$MH0A@@@QAE at XZ"`. The extra `M` might come from qualifier mangling. 

For `x86 msvc v19.24(WINE)` version, it produces `??0?$AutoParmTemplate@$0A@@@QAE at XZ` for both `AutoParmTemplate<0> auto_int` and `AutoParmTemplate<false> auto_int`. Isn't this a bug?
