Public bug reported:
I did an svn update in one of my working copies, and svn crashes after a
'diff -r HEAD' or 'update' (presumably anything that has to connect to
the server). This could be an issue with sasl according to the stack
trace.
Other points of potential interest:
1. My working copy has svn:externals defined, and other archives which do not
have externals defined do not share these problems. I have not exhaustively
ruled out that all working copies with externals defined fail and all that do
not have them defined do not fail.
2. I'm using JavaHL/libsvn through the Eclipse IDE to do SVN updates, which is
how I saw this originally, but I also see it when using the svn commandline.
It's possible that Eclipse has corrupted something that now causes this to fail.
Here is the gdb stack trace with debugging symbols. I scrubbed the
repository info but left placeholders (aaa, bbb, etc.) that synthesize
the externals definitions correctly.
warning: Can't read pathname for load map: Input/output error.

Core was generated by `svn update'.
