             Bug #: 13123
           Summary: dlopen() leaks 8 bytes on each time used against
                    regular binary like /bin/ls
           Product: glibc
           Version: 2.12
            Status: NEW
          Severity: normal
          Priority: P2
         Component: libc
        AssignedTo: drepper.fsp@gmail.com
        ReportedBy: itakingiteasy@gmail.com
    Classification: Unclassified

Simple testcase reproducing the bug

This is might be a false positive, but valgrind reports about leak of 8 bytes
each time dlopen() called aginst regular binary like /bin/ls. I am attaching
simple test-case illustrating the problem - each time it's load() function
called valgrind reports about additional 8 bytes lost.

My system is Gentoo/amd64/libc-2.12 (but same problem is also exists on my x86
gentoo notebook and was confirmed by many people on irc with various distros
and glibc versions).

Noteworthy that this valgrind report can be avoidid by using tcmalloc/jemalloc
instead of regular glibc malloc.
