Summary: crash on redirect with basic-auth

Initial Comment:
PHP was crashing on me in libcurl, so I checked the
command line version and it had the same problem which
occurs when I try to follow a redirect and use basic
authentication at the same time.

I've checked with 7.6 and 7.7-beta3 with the same
result. The backtrace is from the former:

gdb curl
(gdb) r -L -
i "http://user:pass@194.68.213.78/se/info.nsf/CurrentNe
ws/FEDB074667F3B44BC1256A0E003B5430?Navigate&To=Next"
Program received signal SIGSEGV, Segmentation fault.

1413 if(*data->userpwd != ':') {
(gdb) bt

(gdb) p data->userpwd
$22 = 0x0

You see, data->userpwd is NULL, it gets reset somwhere.
