Hi, gnu.org glibc group have changed 'libdl memory leak' ticket status to
'closed'. Please find attached final patch which have been applied to
glibc2. It is done relatively glibc-2.0.7-19.src.rpm RedHat SRPM. If this
patch is applied Andrew's libdl test program and Mihai's pwchecker PAM
test program does not produce memory leak. 

Regards, Victor Kamensky
