Are there any known compatibility issues with the Intel Threading Building 
Blocks (TBB) memory allocator on Linux?

I have narrowed down a problem I have to a very small (well, basically empty) 
C++ program that links to both QtCore (our GUI framework) and libcurl.so.4 
(7.21.0 dynamic version) and crashes at exit.  No other libraries are linked 
into the stub executable.

Stack trace and valgrind show invalid free of some static Qt objects. I think 
this is just a red herring for earlier corrupted memory.

Using native glibc allocator is fine.

Will post more later, just checking if anyone is using the threading building 
blocks allocator or Qt with libcurl.


P.S.
 Does Qt have a copy of libcurl statically linked inside it?  We're using 
Commercial Qt 4.7.0. I wonder if it's possible there is a conflict.
