DLL newly returning garbage with MT5 build 1036

[chinaski]

Hello,

have a DLL with a function returning string (wchar_t*), so unicode.

The DLL was not changed since long time and work 2 weeks ago with MT5.

But with new build, this DLL newly return garbage.

The DLL has log, where i log the value returned right before returning and at this state, the string is ok.

 

But when calling the function from Expert:

int id=103;
string sname=DLL_GET_NAME_BY_INDEX(id);

 sname is garbage.

I checked all, delete .ex5 , recompile, no change.

Has anyone else this problem ? (may a solution)

Thank you

Checked it out: 

The code above works correctly with build 975.

It works not correctly with build 1010 and build 1036. 

 

What has been changed ?
