Instance variables overwritten by other assignments

[Patryk Laurent]

Hi,

At Gorm startup I am seeing a problem where Boolean assignments in 
-initDefaults are somehow overwriting memory for NSTableView.m’s 
_numberOfColumns instance variable.  See the output of debug print statements 
below. 

Does anyone know why this might be happening — and how to fix it?

This is under clang-6.0 on Aarch64. 

Thank you,
Patryk
