I had this thought:

symbol name information available to it. It clearly printed gibberish here.
In addition to this impossible sequence of calls, there were also four
"unknown" functions in that trace. That might be plausible if the svn
libraries were used from within an application but the OP reported using
svnadmin on the command line. This leads me to believe that addresses were
mapped to incorrect names, and as such the access violation probably didn't
occur in svn_fs_print_modules().
