Subject Bogus HOME causes segfault
Date Mon, 28 Apr 2014 17:19:03 GMT
I know this probably falls into the "Doctor, it hurts when I do this" 
category, but I found a probable bug in Subversion 1.8.5 where an 
invalid HOME directory results in a segfault.  For example:

$ HOME=/dev/null svn --version
svn: warning: W000020: Can't open file '/dev/null/.subversion/servers': 
Not a directory
Segmentation fault (core dumped)

This does not happen with versions 1.7.8 or 1.6.16 (the other two I had 
handy).  On those, it gives me the same warning, but does not segfault.  
I have yet to try 1.8.8 as I don't have it installed anywhere yet.  This 
also happens with an unreadable directory (i.e. /root), but it does not 
happen if given a nonexistent directory (i.e. "/foo/bar")

Why do I care?  The php script with repos-web does an svn log, and the 
HOME environment variable ends up containing "/root" which is not 
readable to the repository owner.  I have implemented a workaround, but 
it seems to me that a segfault is never a good answer, even if I am 
doing something stupid :)
