Thank you for the report. Can you send a copy of your forked escrow code? And the value of $APPROVE pass in here? wasmcli tx wasm execute fred $CONTRACT "$APPROVE" -y.

The contract should fail. If not, I will investigate further and fix it.

As to the error message / stack trace when hitting ctrl+C, this is an odd known issue that doesn't affect the chain performance but is worrying on restart. I will create a new issue for this.

This has been fixed with wasmer 1.0.0, used by cosmwasm-vm 0.13.

Fix is on master as of #358 and will be on the v0.14.0 release. Took a year, but this looks a lot nicer now.
