If you could retrieve a romlog from the camera that crashed, that could give some hints.

I get a RomLogErr.txt with "Log is not Saved." inside on G7, A450 and A470.

ROMLOG.LOG from S2 is attached.

A630 ROMLOG.LOG contains:

Try again with CHDK 1.2, changes in 1.3 may cause compatibility issues with older modules.
Thanks, that was the perfect hint. I think I even had a CHDK 1.2 on the A560.

So let's get started.
Here is the dump of: S2IS 100F

There are cases when the camera can't record a romlog.

Undefined instruction, call from thumb code to ARM, CPU is in ARM mode, the RAM either contains garbage or thumb code. I'm using an ARM routine for memory copy, perhaps doing that is not a good idea. (Excuse the tech details)

Thanks for the dumps, BTW.

And the (EDIT: almost) final one for today: PowerShot A450 1.00D
I'll look at the still older cameras another time (soon).
I might have one or two more.
