(ITS#5623) slapd segfaults on syncrepl provider

Full_Name: Matthias Grau Version: 2.3.43 OS: irrelevant URL: Submission from: (NULL) (195.200.70.23) Slapd segfaults on a syncrepl provider. This error occurs when the connections of several synchronous modify operations are not disconnected correctly (e.g. network issues). syncprov.c line 1707: m2 seems to be NULL in this case so m2->mi_next causes the segfault. Program received signal SIGSEGV, Segmentation fault.

Howard says there should have been some packet dumps that would have included the protocol error, but I must have missed them amoungst all the noise of level -1. A nice error message at "none' would have helped. -- Paul B.

OK, I have to accept this. As my local CVS tree is only a weeky update and not a fresh checkout there might be some errors in the test scripts, as -iB works for me, I leave it as is.
