Re: [Valgrind-users] Valgrind doesnot show any memory Leaks

[Julian S. <js...@ac...>]

I think we saw recently (last couple of months?) a case where Memcheck
didn't do any intercepts with uClibC, and it turned out that the problem
was that uClibc had not been built with LD_PRELOAD support.  So the
intercept .so never got loaded into the process.  I wonder if that is
the case here?
