OK. So that means that either membuffer isn't the cause of the error,
or both membuffer and inprocess have (independent) bugs.

That said, I'm happy to see that it took you less than a day to report
that the bug no longer reproduces. Can you reproduce it at will?

---
I'm not completely sure what to try next.  Were there any other
significant changes in 1.6.x->1.7.x besides caching?  If so, the
next steps would be to disable _both_ inprocess and membuffer, or
to bisect.
Unfortunately, the latter requires building svn from source, and the
former requires either that, or having you upgrade to specially-built
binaries, or squeezing the "disable inprocess" feature into 1.7.4 (in
a way that doesn't break our compat policy too badly) and having you
upgrade to that.
devs/all --- thoughts?  Is there a simpler way forward than the two
potential 'next step's I've outlined here?
