The OOM is probably triggered by the sheer amount of changes it has to merge,
IIUC correctly you are trying to merge a branch back to trunk. If you could
merge those changes in smaller steps, each individual step would require less
memory. For that I would try to first to only merge revisions. If there is
such a revision that has so many changes to so many and large files that it
already triggers the bug, you could also switch to merging single files or
directories or maybe even merge manually and only mark the revision as
merged.

I've been using branching and merging regularly, and I've never encountered
this problem. I'm wondering if it's not some other kind of bug you encounter,
like e.g. an endless recursion or something like that. This could also
manifest as OOM, but no amount of memory would fix it.

You could move the line ending issue by moving it back to the Ubuntu machine
after testing it elsewhere.

Good luck!
