Crash when saving control config.

[Alcom1]

Crash occurs immediately after saving a control config in the "Control Config" menu.

Before the crash, there were other issues with saving the control config.

• Could not overwrite existing config by saving it under the same name.

• Deleted existing config, but still go the "cannot overwrite" message when saving under the same name again.

Do you get the same error when running vanilla FSO? I suspect it may be something on SCPUI's side.

[wookieejedi]

Same, I also concur it's likely SCPUI

Here is the stack trace from the minidump. It does seem to be SCPUI related.

I can't really understand the code fully, but based on this, I'm guessing something caused SCPUI to use up too much stack space?

This might also be relevant. The variable that keeps track of how much memory was being requested, realsize, either wrapped or is junk memory that the Dump recorded:

This is indeed an SCPUI bug, and a fix has been pushed to SCPUI master here: https://github.com/MjnMixael/SCPUI/issues/13

This can likely be closed as completed

[MjnMixael]

Additionally it is now fixed in the next SCPUI version. So it can be doubly closed.

Right, if it's fixed in SCPUI, closing this issue
