Re: [osg-users] referenced memory management across dlls/exe (Windows only)
Thanks Sergey. I found that too. The problem was that the a core lib was keeping a ref_ptr of an Object allocated by a plugin from a dll. Then on clean I got this problem. I solved it by changing the ref_ptr to observer_ptr in the core lib. So I am good now. But BIG thanks for helping me. Ulrich, thanks too. Nick p.s. I was Windows programmer for a decade and switched to Linux recently. What a difference :-).

Re: [osg-users] referenced memory management across dlls/exe (Windows only)
Hi Nick, after looking some more I found that newer versions of Mingw switch to dynamic linking of libstd++ by default. so libstdc++-6.dll is a right lib. but as you have the same problems then I have no answer.

Re: [osg-users] referenced memory management across dlls/exe (Windows only)
also I am using Qt Creator and MinGW (whatever the last version is). I know
in Visual Studio you can specify the /MD option to use shared CRT libs and
to avoid this problem. Any MinGW gurus around with hints?

[osg-users] referenced memory management across dlls/exe (Windows only)
Hi all,
I am facing a problem with memory clean-up when mixing the place of
allocation across dlls and the executable. Let say I have main executable
that loads dlls (plugins) in which I allocate memory using referenced
pointers. On exit, those pointers that were allocated in one of the dlls
got stucked in
if (needDelete)
{
signalObserversAndDelete(true,true);
}
Ln 198 in Referenced. And this is Windows only, on Mac or Linux I
don't have this problem.
If I clean these pointers from the originated dll, it works ok, otherwise not.
Any clue?
Thanks as allways!
Nick
