Can't overwrite device variables in debug mode

[Ghardo]

In debug mode device variables like Settings or Mode cant be set.

Write a test.ic10 and a test.toml

test.ic10

s db Setting 100
l r15 db Setting 
move r0 1

the last 2 lines are only there to keep the debug mode open

test.toml

[db]
Setting=10

Now start the debug mode and step to line 3.
The new value of 100 are not set in debug mode
