I recently upgraded a system (as far as perl is concerned from 5.8.8

find a workaround, but still don't really understand, what is

After the upgrade, a perl program wouldn't run anymore - it crashed
with a message:"*** glibc detected *** /usr/bin/perl: double free or
corruption (fasttop): ..." and a memory map suggesting some
problem on
the heap.
I've seen that error message when the version of glibc changes. Have
you
tried re-installing Net::LDAP so that is is compiled against the same
libs that your perl is?
Net::LDAP itself is pure perl, so that would not make a difference.
Also this is not due to the library any program is linked to. In newer
versions of glibc they added a this warning for when free() is called
multiple times. I forget the versions, but we saw this in a lot of
apps at a previous employer when they upgraded RHEL, which introduced
the new glibc
Graham.
