The really interesting thing here is the 'svn merge --force' Without the '--force' the merge just succeeds without a problem. That would be really useful information to add to an issue... When I tried to create a reproduction recipe as part of the testsuite that was something I missed... With Subversion 1.8 I would really recommend not using this argument. Before 1.8 the merge infrastructure couldn't really test if a directory delete was exactly valid, while with 1.8 we resolved that problem. We just don't have many tests that use this '--force' and that is what triggers the segfault for you. I would assume a bugfix will be in the next patch release as this problem is most likely easy to fix. (I expect that I have a patch in the next half hour) Bert
