Hangs for me too. Win 7 32-bit with Cygwin 1.7.2-2, Sophos Endpoint Security and
Control 9.0.4 with the Anti-Virus service disabled.
strace log at http://129.217.163.1/%7E%6D%61/tmp/svn_version-hang.txt.xz
gdb is inconclusive; if I run "gdb svn" and "b main", gdb breaks at exit and
then goofs up down deep in exit. If I use kill -9, gdb breaks again and I get:
(gdb) bt
#0 0x00000000 in ?? ()
#1 0x77ca5e4c in ntdll!ZwWriteRequestData ()
 from /cygdrive/c/Windows/system32/ntdll.dll
#2 0x75e66872 in KERNELBASE!GetProcessId ()
 from /cygdrive/c/Windows/system32/KernelBase.dll
#3 0x00000002 in ?? ()
#4 0x0022c81c in ?? ()
#5 0x00000001 in ?? ()
#6 0x00000000 in ?? ()
I guess this doesn't help.
Interesting observation: run "gdb svn", "b exit", "run --version"; gdb breaks:
...
* ra_serf : Module for accessing a repository via WebDAV protocol using serf.
 - handles 'http' scheme
 - handles 'https' scheme
Breakpoint 1, 0x61112df7 in exit () from /usr/bin/cygwin1.dll
(gdb) bt
#0 0x61112df7 in exit () from /usr/bin/cygwin1.dll
#1 0x61006e7b in _cygwin_exit_return () from /usr/bin/cygwin1.dll
#2 0x00000000 in ??
makes some sense, but then if you run "s" or "c", it hangs. So it appears as
though the hang happened in exit() somewhere. Same with svn --help.
This appears to be specific to svn; svnlook, avnadmin aren't affected on my
computer.
This is the unified diff of "cygcheck /usr/bin/svnadmin" vs. "cygcheck
/usr/bin/svn":

Might of the additional libraries may have regressed? From the strace log, I
suspect cygsasl2, which itself loads libraries, for instance
/lib/sasl2/cygplain-2.dll and /lib/sasl2/cygsasldb-2.dll on my computer
(cygsasldb-2.dll is the last before the hang).
I've also run rebaseall, to no avail.
