[Frama-c-discuss] Issue with -save/-load options, warning not displayed in GUI

Hi David,

This is not a bug. By default, warning are not stored in the save
file. However, the option -collect-messages is what you are looking

(We are trying to transition to a state where all alarms emitted by
Value are stored as ACSL properties, so that the 'messages' panel will
ultimately be fully redundant. We're not there yet, though.)
