both versions are 32bit alright

thanks, IOhannes. that was the right hint !

actually it was "pthreadVC.dll" in the BIN folder that caused the error. 
the self-compiled PD had its accompanying file "pthreadVC.lib" dated 
from 2002, whereas the .dll was from 2018. i figure here's the mismatch.

so i exchanged the new "pthreadVC.dll" with the old one from the 
official .zip package and Gem loaded and worked fine !
