That's the apr_poll() call in data_available_handler_apr() failing, and
E000009 could be EBADF. I suppose the file could have been closed, or
the file descriptor could have been overwritten. What do you see in the
debugger?

Breakpoint 2, data_available_handler_apr (baton=0x669500,
    data_available=0x7fffffffdccc)
    at ../src/subversion/libsvn_subr/stream.c:955
955 status = apr_poll(&pfd, 1, &n, 0);
(gdb) p pfd.desc.f[0].filedes
$6 = 6

On Linux I can check that 6 a valid file descriptor for this process:

$ ls -l /proc/28574/fd/6
lr-x------ 1 pm pm 64 Aug 14 10:18 /proc/28574/fd/6 -> pipe:[612259]
