A bit more debugging would be useful. I debugged this on native Windows and the code is not accessing a negative index to the domain list anymore. From my POV *this* part of the code is working as desired. > Here is some strace.exe output: >=20 > 228 142321 [main] bash 11 __get_lcid_from_locale: LCID=3D0x0409 > 659 142980 [main] bash 11 pwdgrp::fetch_account_from_windows: line: > > 715 143695 [main] bash 11 pwdgrp::fetch_account_from_windows: line: > > 146 143841 [main] bash 11 pwdgrp::fetch_account_from_windows: line: > > 141 143982 [main] bash 11 pwdgrp::fetch_account_from_windows: line: > > 155 144137 [main] bash 11 pwdgrp::fetch_account_from_windows: line: > > --- Process 11, exception c0000005 at 6113FD85 That's a crash in wcsncpy. Where's the NULL pointer coming from? The pointer I created for the domain name points to an empty unicode string, it's not NULL. Oh, hang on. On Windows, the name part of the logon sid is the login sid as=20 a string. So, if the login sid is S-1-5-5-0-1234, the name of the sid is L"S-1-5-5-0-1234". Is it possible that Wine doesn't reflect that?
