| I seem to have found a problem with the $monitor task/events. |
| (this is probably related to bug 399) |
| The problem only seems to arise in vvp mode and not in vvm. |
| Problem: $monitor seems to lose both the first and last time steps. |
| |
| A complete copy of the run follows with source appended at the end. |
| (The correct output from vvm is shown in the last run) |
| This file compiles and produces the problem. |
