memory leak with dlopen dlclose

[shw]

version : uclibc 0.9.29 (mips)
My code needs to open various shared library, and execute the lib function dynamically.
I think dlopen/dlclose was the best approach for me, but I encountered the memory leak
issue as following item,

Is there any update on this issue? Or any suggestion would be appreciated.

Thanks,
