Excel has exited with code -1073741819 (0xc0000005) 'Access violation'

[Chris Keenan]

Hello,

We have an XLL plugin that uses Excel DNA and NetOffice. Ever since build 1802, a certain call to worksheet.Calculate() crashes Excel. Since it's Excel that has thrown the Access Violation, I'm unable to capture that exception in the managed .NET code. 

I've stepped through the code multiple times, and each time worksheet.Calculate() is called, the Excel crash happens at a different stage. 

Anyone aware of a way to hunt down the suspect code? Since the code works with 1801 and prior, it would point to a defect or change in Excel itself. But I'm searching for a way to find the problematic code in our source.

Thank you,

Chris
