Thanks for the reply. My link line is

When it turns, it segfaults at exit (cleaning up some Qt static data):

Removing QtCore or libcurl from the link line generates a successfully running
program.
Removing just TBB proxy (that enables the TBB allocator) also generates a
successfully running program.
Mysterious!

I am developing a linux application in C++, which uses Qt 4.7.3 LGPL version,
libcurl 7.24.0 and TBB(but not it's memory allocator). It might be too early to
say, but I haven't faced any issue yet.
