Access violation error after creating Route Event Layer

Question asked by Greg.Young on Jan 8, 2018

ArcGIS Pro has been crashing after I run the Make Route Event Layer tool.  The layer is being created from an Oracle SDE database.  When I run the Just-In-Time debugger, I see the following exceptions:


Unhandled exception at 0x00007FF9A8A63C58 (KernelBase.dll) in ArcGISPro.exe: 0xC0000005: Access violation.


Unhandled exception at 0x00007FF9567E7094 (RouteEvents.dll) in ArcGISPro.exe: 0xC0000005: Access violation reading location 0xFFFFFFFFFFFFFFFF.


The Disassembly breaks on this line:


00007FF9567E7094  call        qword ptr [rax+8]  


Here complete disassembly is attached.  


Can anyone offer some insight into what is happening here?
