It happened with me in one of the projects with 5.1 FP4 Rev D.
If the Profibus Slave with a DTM/Gsd based device type is already added in Hardware tree under CI854 and if you make any changes under GSD editor at library level and download it directly, then it causes a memory violation of a kind and there is a high chance of Controller crashdown.
Not sure there will be any Patches to rectify this.
But recomended Workaround is
1. Remove the Device type instances under CI854 of Downloaded program before making any changes in GSD editor at library level.
2. After removinng download to controller and make the memory free under those slots.
3. Now add the slaves back with updated configuration and then download.
