A crash when a pool is destroyed means that there was at least one
memory block not released properly. The svn library has added a check
function for that when destroying a pool - if it finds one block that
wasn't released, it calls abort().

I've tried to reproduce this with an unauthenticated svn repository and
that doesn't crash.
Even with an authenticated one, it works. Maybe it's required to use
SASL authentication to get the crash?

Can you please try the command line client (if you've selected it during
install of TSVN, you already have it in the TSVN bin dir) and run:

svn ls -v svn://somewhere

and see if you get an abort/crash with that as well?
If you do, you should report this on the Subversion mailing list.

Also, please check the file dates in c:\program files\tortoisesvn\bin of
libsasl(32).dll and all the sasl*.dll files: if their date is not the
same day as the other dlls and exe files, you have to run a repair
install of TSVN.

Since I only keep the debug symbols of official releases, I can only use
crash dumps for those. That's why the crash feedback dialog is
deactivated for the nightly builds.
