Non-deterministic gas usage after node restart when writing to realm storage

[omarsy]

Description

Gas usage for the same transaction that writes to realm storage is not deterministic and changes depending on whether the node has been restarted.

Steps to Reproduce

Test 1 (restart)

gnoland start

gnokey maketx addpkg -pkgdir $WORK/realm -pkgpath gno.land/r/foo -gas-fee 1000000ugnot -gas-wanted 20000000 -max-deposit 502500ugnot -broadcast -chainid=tendermint_test test1

gnoland restart

gnokey maketx call -pkgpath gno.land/r/foo -func NewFoo -args "foo"  -gas-fee 1000000ugnot -gas-wanted 10000000  -broadcast -chainid=tendermint_test test1
stdout OK!


-- realm/gnomod.toml --
module = "gno.land/r/foo"

gno = "0.9"

-- realm/storage.gno --
package foo

var record *Foo

type Foo struct{
  name string
}

func NewFoo(cur realm, name string){
  record = &Foo{name}
}

Result:

stdout OK!
GAS USED: 258357

---

Test 2 (without restart)

gnoland start

gnokey maketx addpkg -pkgdir $WORK/realm -pkgpath gno.land/r/foo -gas-fee 1000000ugnot -gas-wanted 20000000 -max-deposit 502500ugnot -broadcast -chainid=tendermint_test test1

gnokey maketx call -pkgpath gno.land/r/foo -func NewFoo -args "foo"  -gas-fee 1000000ugnot -gas-wanted 10000000  -broadcast -chainid=tendermint_test test1
stdout OK!


-- realm/gnomod.toml --
module = "gno.land/r/foo"

gno = "0.9"

-- realm/storage.gno --
package foo

var record *Foo

type Foo struct{
  name string
}

func NewFoo(cur realm, name string){
  record = &Foo{name}
}

Result:

stdout OK!
GAS USED: 252481

Expected Behavior

Gas usage should be identical for the same transaction

#5008 (comment) should fix it.

not fixed until a pr fixing it is merged
