How to make subversion 0.32.1 crash:
cd <random workspace>
touch <random versioned file>
chmod 0 <same random versioned file>
svn st
Segmentation fault
strace gives:
...
stat64(".svn/text-base/fooblaa.txt.svn-base", {st_mode=S_IFREG|0444,
st_size=0, ...}) = 0
open("fooblaa.txt", O_RDONLY) = -1 EACCES (Permission
denied)
--- SIGSEGV (Segmentation fault) ---
and the backtrace is:

This is on Linux, btw.
I assume it's a simple error of some code not handling EACCES
correctly, but if you can't reproduce the error I can investigate it
further.
