The problem seems to be that std::has_facet looks for a Facet with an id of 46 (0x2e). But when it gets to this line:
const facet *_Facptr = _Id < _Ptr->_Facetcount ? _Ptr->_Facetvec[_Id] : 0; // null if id off end
_Facetcount is 46 so it decides it's off the end. I notice that in the working version _Facet::id is 44 (0x2c).
Till I get to VS at evening so I'll be able to answer. Few questions:
1. Are you using statically or dynamically liked boost.locale?
Static
2. Are you using statically or dynamically liked boost.test?
Static
3. If you use dynamically liked versions do you specify correct import defines?
N/A
4. The last what parameters of CMake did you used when you build boost.locale library.
I'm afraid I don't understand the question
5. I really hope that after build you did not switch Debug/Release from the MSVC project but rather prepared two solutions with passing correct options to CMake?
I generated the single solution using CMake which puts a debug and release configuration in the same file. This is how it's supposed to work, right? I didn't run CMake twice to create two seperate solutions.
Any idea what's happening here?
Yes... This is what called why I love dlls very much ;-) ...snip... So it is very easy to screw everything up when using dlls and static class members...
So what happens something somehow didn't used everything correctly. So you should be extremely careful when creating or using DLLs.
I'm not using DLLs here! My repro code does it with a simple EXE. All it takes is a single static locale instance. This may even repro on Linux.
Each facet type should have specific unique id which is static member of facet class (std::locale::id).
If this id is not unique - two different ids would be created and thus there would be mismatch of facets and you would not be able to use them.
Where are these ids generated? I tried to find it but it seems that they appear by magic :P
P.P.S.: I'll take a look on the code you gave today or tomorrow.
Thanks! Alex
