GMAT 64 bit can be made to crash easily, at least on my machine, by:
- Start GMAT 64 bit
- Click New Script button
- Close Welcome Page
- Close Script Window using Close button
- Start GMAT
- Add Report File
- Run GMAT Mission
- Open Report File in GMAT
- Close Report File Window using Close button
It looks like it happens in wx (3.0.2) code.
I cannot reproduce this on LatestCompleteVersion 32 bit. Someone needs to confirm this for 64 bit.
