Hi,
We suddenly have a new test failure on NT4 and above for advapi32:security :
security.c:1202: Test failed: GetTokenInformation failed with error 998
998 = ERROR_NOACCESS -- "Invalid access to memory location."
Google (http://www.google.co.uk/search?q=ERROR_NOACCESS+GetTokenInformation&btnG...) found http://www.cygwin.com/ml/cygwin-apps/2008-04/msg00222.html:
"For whatever reason, GetTokenInformation was failing and returning ERROR_NOACCESS when passed a 1024 byte buffer. I changed the code to first call it with NULL to get the desired size, and that seems to have satisfied it. I cannot explain why it would object to a 1024 byte buffer, maybe you have some idea."
That thread seems to suggest that this is an alignment issue -- the GetTokenInformation wants the buffer to be aligned properly. Corinna Vinschen suggests using
PTOKEN_GROUPS groups = (PTOKEN_GROUPS) alloca (size);
as alloca aligns correctly in cygwin's case.
The buffer used in the test (line 1199) is allocated on the stack as a standard array and is thus not guaranteed to have the correct alignment.
And now also the rpcrt4:server test on W2K3 crashes (which it didn't before) although that crash is not shown on test.winehq.org (child process crashing?) but you will see 13 failures for this test (0 before).
I haven't found the variable yet. I'm running VMware but I also see the advapi32 failure on a real box. My VMware image for W2K3 hasn't been updated since last week.
No idea for this one. Have you done a bisect?
