I did this, like this:

To refresh people's memory, here's the command that fails:

$ ../src/curl http://127.0.0.1:8999/91 --anyauth -u mydomain\\myself:secret

When I add -v, it works.

The debug output looks like this:

conn->headerbytecount (k->hbuflen) is 46
conn->headerbytecount (k->hbuflen) is 88
conn->headerbytecount (k->hbuflen) is 123
conn->headerbytecount (k->hbuflen) is 147
conn->headerbytecount (k->hbuflen) is 187
conn->headerbytecount (k->hbuflen) is 232
conn->headerbytecount (k->hbuflen) is 251
conn->headerbytecount (headerlen) is 253

(Without -v, when it fails, the debugging stops here)

conn->headerbytecount (k->hbuflen) is 52
conn->headerbytecount (k->hbuflen) is 79
conn->headerbytecount (k->hbuflen) is 99
conn->headerbytecount (k->hbuflen) is 144
conn->headerbytecount (k->hbuflen) is 385
conn->headerbytecount (headerlen) is 387
conn->headerbytecount (k->hbuflen) is 54
conn->headerbytecount (k->hbuflen) is 81
conn->headerbytecount (k->hbuflen) is 126
conn->headerbytecount (headerlen) is 128

I'll see if I can figure out why...but in case someone gets there first...
