compiler error in ivy1.8 : invalid conversion from ‘int’ to

[prpr2770]

The issue I've indicated below is similar to the one that was raised earlier in #57. It provides a more concise representation of the problem.

The ivy-script for modelling a connection-mgmt protocol check correctly, withivy_check OK.
However, when compiling it using ivyc target=test conn-mgmt.ivy, we obtain the following error:

$ ivyc target=test connection_mgmt_v2.ivy
