| Summary | 0000537: segfault when exiting PyGTK | ||||
| Description | The following segfault is seen when loading models/johnpye/fprops/combinedcycle_fprops.a4c into the PyGTK GUI (pygtk/ascdev) and then immediately quitting from the GUI. It is not necessary to instantiate a model. The bug appears in changeset 3922. In changeset 3921, there is no crash. The bug presumably arises from the LINK syntax additions merged into trunk at that stage. | ||||

This also appears when reloading models in some cases (with ExtPy in action). Could also be something to do with new SOLVER, OPTION, SOLVE keywords? |

() Actually it's not necessary even to instantiate the model in order to get this error, it seems. Which seems odd. |

This bug was introduced in changeset 3922, which was when Dante's work was incorporated into trunk from Ksenija's branch. |
