[Bug 902345] [NEW] svn (or products using libsvn) crash after operation in libsasl

Fri Dec 9 21:14:12 UTC 2011

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.
