Powerbuilder 12.6 \MSVCR100.dlL Crashing

Question

Hello;
We just upgrade our application from powerbuilder 12.1 to 12.6.  The code migrated and deployed correctly. 
When we release it to a user for testing randomly and I mean randomly not duplicate-able at will the deployed application crashes.
Below you will find the event log from windows.
Please note we have deployed all the recommend DLL's to include the following old and new code.
atl71.dll
atl100.dll
msvcp71.dll
msvcp100.dll
msvcr71.dll
msvcr100.dll

Hi Ed;
  WOW .. this sounds like this might be a PB 12.6 issue. 
BTW: I would check the atl71.dll, atl100.dll, msvcp71.dll, msvcp100.dll, msvcr71.dll, msvcr100.dll file sizes and dates on the redistribution package vs what PB 12.6 installed in its "shared" folder.
FWTW: Sounds like you might need to open a support case with SAP on this one.
Suggestion: Can you try a lower PB release - like 12.5.x? FYI: Many of my Canadian Government clients are in production & running solid using PB 12.5.1 currently.  
Regards ... Chris
