I can reproduce this issue, but I don't anticipate investigating it.

I have yet to package the latest Subversion release. I no longer use
Subversion and the build process is quite complicated. Maintaining the
Cygwin port has always been near the limits of my abilities, and since I
no longer use Subversion, I've simply lost interest.

If you would like to take over maintenance of Subversion, I'd be happy
to support you as much as I can. ;-)

serf switched to scons as a build platform. scons is written in Python
and aims to replace autoconf/automake. scons knew nothing about Cygwin
when serf switched to it, so I had to teach it to build Cygwin stuff. I
am NOT a Python programmer, but I managed to get it working. Well,
everything except the debug packages.

If you know Python, please have a try fixing it.

Otherwise, you can rebuild serf from source with debugging enabled and
without stripping the symbols. There's a section of the .cygport file
commented out to do this.
