Hi Daniel/Joaquin,

Please find my answers to your questions below,

[

#include <new>

int main() {
int space;
void* ptr = &space;
new (ptr) int();
}

If that works okay, try also including the headers that you use in
your project to see if any of them cause it to stop working.

]

Yes, a fresh project with this program works. The only new header I had to add is "boost/unordered_map.hpp". Adding that did not cause any compilation problems

[

It might be an issue with precompiled headers. Someone solved a
similar problem by turning them off:

]

I suspected this previously, but turning this on/off did not cause any issue is stand alone programs using multi_index/unordered_map.

[

Along that line, Ram, could you please verify if your project uses DEBUG_NEW somewhere? Don't forget to check for macro definitions on the project's properties window.

]

I did a search for DEBUG_NEW and didnt get any results. I also saw that the only preprocessor defines we have are,

WIN32

_DEBUG

_CONSOLE

V_DEBUG

Thanks,

Ram
