Attached test app makes memprof think memory is slowly leaked, but it doesn't look like it really is.
Created attachment 91181 [details] test app that creates confusion
When I run this program (not under MemProf) the program slowly gets bigger as shown in top ... maybe 20/30k per second. I suspect it's just leaking. [ Havoc later commented that valgrind also shows a leak ] You probably need a NIS setup to reproduce the problem.
I've checked in a patch in the official glibc CVS archive. The next RPM will contain the fix.
