--- Comment #1 from François Gouget fgouget@codeweavers.com --- It is strange that opening the event log only fails on two test configurations.
So I did some tests on w10pro64v2004 and test_backup() crashes the event log service on that machine. Paradoxically, after a reboot (or if I wait long enough) I can even see an event telling me so:
Source : Service Control Manager Event ID : 7031
The Windows Event Log service terminated unexpectedly. It has done this 1 time(s). The following corrective action will be taken in 60000 milliseconds: Restart the service.
Specifically it's the call to make a backup of a backup that causes the crash:
/* Can we make a backup of a backup? */ handle = OpenBackupEventLogA(NULL, backup);
Furthermore test_backup() is not the only part of advapi32:eventlog that causes the event log service to crash. But tracking the other service crashers is still to be done.
