When we try to commit a very specific version of a very specific
binary file, we get a SHA-1 collision error from the Subversion
repository:
D:\confidential>svn commit secret.bin -m "Testing broken commit"

Could the collision be in a
"diff" instead of the files themselves?

The line from the grep -a command containing that hash is below. They
all match.

how to proceed is to wait until the source code to
TortoiseSVN is available so that I can debug it in Visual Studio. Is
there something else I can do?

The problem is identical on Windows command line, Windows TortoiseSVN,
Ubuntu-Linux, Ubuntu-Linux on Windows, and macOS. I'm just bad at
GDB.

How can I dump out the two things that Subversion thinks have the same
SHA-1 checksum but don't match? This seems to be rather difficult to do.
That said, it's far more likely that there's a bug in Subversion than that
we randomly collided SHA-1.

first_rep->size is 16384, and this is why rb->len becomes 16384,
leading to the error.
I don't know what all this code is doing, but that's the proximate
cause of the failure.
