Re: Segmentation fault on svn status

OK, I figured out what the problem was.

Very important (as it turns out) piece of information that I forgot:
I copied the svn executable from subversion/clients/cmdline/svn to the top
of my working copy of Subversion and *used that copy*. When I use the
original subversion/clients/cmdline/svn then everything behaves as expected
(no segment faults).

So in response to your question below, yes I did change something :-)

However, now the issue becomes: A copy of the svn executable cannot run 'svn
status' and behaves strangely for other commands. Should this be regarded as
a bug? Or just user error for not linking to the original executable (or
using make install)?

Actually, I copied the svn executable.

I tried running gdb on my svn copy, but it complains that it is an unknown
file type.
Ahhh...now I notice that svn is actually a shell script?! How do I debug
this with gdb??

>(gdb) run status -u (or whatever arguments you give to the svn command)
