#2685 Segfault in FGPUIDialog::applyValues

[legoboyvdlp]

I've received reports of reproducable segfaults in the f16 when changing stores. The backtraces are attatched. As best I can tell, the segfault has something to do with the call to propertyObjects[i]->node within FGPUIDialog::applyValues.

applyValues() is the function called on the "apply-dialog" binding.

propertyObjects is a vector of PropertyObject, which is a struct containing an element 'node'. This element is a SGPropertyNode_ptr (SGSharedPtr).

Users are both on Linux, one on next, and the other on the 2020.3 AppImage.

No such crash occurs on Windows.

Does the F16 have any erros/warnings on the console prior to the crash? Just wondering if the dialog is slightly malformed, although that would presumably crash on Windows as well. Hmmm.
