Subject: Subversion segfaulting
To: cygwin AT cygwin DOT com
Content-Type: text/plain; charset="UTF-8"

After quote a long time I needed to use Subversion and I found it
segfaulting, reproducibly, when I try checkout. I have tried `svn
help` but that does not segfault. I have tried to run `svn checkout
http://svn.apache.org/repos/asf/maven/plugins/tags/maven-javadoc-plugin-2.10.4
maven-javadoc-plugin`. The crashing thread does not seem to have any
decodable call stack. The best I could do is this bit of `strace` log:

Cygcheck does not show anything unusual. This is with Cygwin
2.8.0(0.309/5/3) on AMD64.
