Svn segmentation fault on fresh (10.15) install

I’ve just moved to macOS 10.15 Catalina, discovered to my dismay that svn is no longer included, and so I installed homebrew, and then used that to install subversion.

It seems to have gone OK, but when I try to use it, I get a segmentation fault.

I am at a loss. There don’t appear to be any options for the subversion installation. Any idea how to track this down? Has anyone else managed to get the svn install to work?

What does brew config and brew doctor say?

Please see this (likely related) issue here, in particular my comment:

As I (and other maintainers) can’t reproduce this bug it would be good if our users could help us figure this issue out and propose a patch.

% brew config

It’s not clear to me how that’s related; I’m not using git in any way.

Today I did a fresh svn checkout of the entire repo (it’s quite large). That completed successfully, and a svn update appears to work in any directory. But svn status either (1) immediately dies with a segmentation fault, or (2) reports absurd results where most of the files it downloaded (and which are, in fact, right there) have a “!” status, and it lists a “?” status on nonexistent files with weird names like H?\85?\C0?\84?\92.

I’m not 100% certain this is always true, but so far it appears that if I do svn status in a directory with no subdirectories, I get failure (1); and if I do it in a directory with at least one subdirectory, I get failure (2).

I would be delighted to help you track this down. What can I do?

In case it’s helpful to see what the absurd output looks like:
