When compiled with total memory under 1 wasm page, the JavaScript console reads:
Gamestate pointer: 1179256
Called draw with counter: 1
Called draw with ptr: 1114248
data[ 0 ]: 43
data[ 1 ]: 43
data[ 2 ]: 5
data[ 3 ]: 5
data[ 4 ]: 5
Called draw with counter: 2
Called draw with ptr: 1114248
data[ 0 ]: 44
data[ 1 ]: 44
data[ 2 ]: 5
data[ 3 ]: 5
data[ 4 ]: 5
Called draw with counter: 3
Called draw with ptr: 1114248
data[ 0 ]: 45
data[ 1 ]: 45
data[ 2 ]: 5
data[ 3 ]: 5
data[ 4 ]: 5
(as expected)
When compiled with say 67_000, I get this instead:
Gamestate pointer: 1181256
Called draw with counter: 1
Called draw with ptr: 1114248
data[ 0 ]: 0
data[ 1 ]: 0
data[ 2 ]: 0
data[ 3 ]: 0
data[ 4 ]: 0
Called draw with counter: 2
Called draw with ptr: 1114248
data[ 0 ]: 0
data[ 1 ]: 0
data[ 2 ]: 0
data[ 3 ]: 0
data[ 4 ]: 0
Called draw with counter: 3
Called draw with ptr: 1114248
data[ 0 ]: 0
data[ 1 ]: 0
data[ 2 ]: 0
data[ 3 ]: 0
data[ 4 ]: 0
In other words, neither the initial Vec value (5) nor the new one
(42 plus counter) is displayed.
Note however that the counter value is still being updated though.
