The problem is the missing of isGlobalCatalogReady attribute in RootDSE in Samba DC. The repadmin will do a string compare of the return value of this attribute against "FALSE" to check if GC is ready. Since there is no such a attribute defined, the Ldap_get_valueW will return a NULL buffer and thus cause the crash on string comparing function. Please add this attribute to RootDSE.
You can check the following KB (http://technet.microsoft.com/en-us/library/cc753809.aspx) for this attribute. Also it is documented in 18.104.22.168.2.10 of MS-ADTS.
Hope it helps.

Subject: repadmin.exe crashing - TTT trace
Erick Nogueira has recently been adding support for DRSGetReplInfo to
Samba, with the aim of making repadmin.exe work against a Samba DC.
Unfortunately repadmin.exe on w2k8r2b is crashing when talking to
Samba. I've extended Ericks work a bit to try to track down the
problem, but I still can't work out why it crashes.
I wonder if you might be able to look at a TTT trace of repadmin.exe?
I've uploaded it here:
The trace was taken on "repadmin /showrepl blu" where "blu" is the
name of a Samba4 DC. The repadmin command was run on a w2k8-r2 box
(build 7600) which was a DC in the domain. It was run as the domain
Perhaps TTT can tell us why it crashes?
