HeapValidate Error: when trying to build the addin with quantlib 1.33.

[kalam360]

I tried to build the addin for QuantLib 1.33 version. Mostly suppressed parts of functions that are causing issue by commenting out in xml. It built and works when I load in excel 2021 (office16). But when I try to close Excel it crashes and addin gets removed.

I run the addin in debug mode and its breaks. the output showing:

'EXCEL.EXE' (Win32): Loaded 'C:\Windows\System32\edputil.dll'. 
HEAP[EXCEL.EXE]: Invalid address specified to RtlValidateHeap( 0000020559CD0000, 000002056FA29BF0 )
A breakpoint instruction (__debugbreak() statement or a similar call) was executed in EXCEL.EXE.

call stack:

This doesn't happen when I build the QuantLib 1.22. I am not sure what causing the error.

The latest supported source code build is 1.22.

Hi Eric,
Thank you for the response. I built the Addin project by updating the xmls, QuantLibObjects projects and solved relevent erorrs with the changes in QuantLib 1.33. Would it be the case that the issue might be with gensrc source code? I have followed the instruction documentation for addin for updated classes and functions. I would really appreciate if you can suggest some places to look or any documentation to go over. Thank you again.
