[Vm-dev] Interpreter simulator error

All,

I stumbled upon the following error when simulating a copy of a 3.8.1 
(6502) image (full log attached) :

Bitmap(Object)>>error:
	Receiver: a Bitmap of length 5499668
	Arguments and temporary variables:
		aString: 	'Improper store into indexable object'
	Receiver's instance variables:
a Bitmap of length 5499668

The simulator loads the image correctly and both validate and 
validateActiveContext tests pass. But when I try to run test, it throws 
this error. VM version is:

4.16.7-3775 #1 XShm Tue May  5 22:44:20 IST 2020 /usr/bin/cc
Linux s400 4.4.0-104-generic #127-Ubuntu SMP Mon Dec 11 12:16:42 UTC 
2017 x86_64 x86_64 x86_64 GNU/Linux

The simulator works fine with 2.2 image but gives error on a 3.8.1 image 
with VMMaker loaded in it.

Has anyone seen this error before? Any help in tracing this bug is 
appreciated.

Regards .. Subbu
