I've been working to debug a problem I've been seeing booting FreeBSD
via HTTPS. I filed a BZ at
https://bugzilla.tianocore.org/show_bug.cgi?id=1917 .


I've done some more debugging and tracked the issue down to attempting to request a file twice without tearing down the http instance in-between. 

In https://svnweb.freebsd.org/base/head/stand/efi/libefi/efihttp.c?revision=349613&view=markup :

If, in function efihttp_fs_open (line 565) I call efihttp_dev_close followed by efihttp_dev_open if the first call to _efihttp_fs_open fails, then everything works. 
But if I don't then I get the crash due to the corruption of the SetSessionDataPointer.
