Openmw-CS crashes when loading large cells as a scene
I am running OpenMW 48 on a Macbook with an Intel chip, using Morrowind files from Steam. I'm encountering regular crashes when working on .omwaddon files in the CS editor. The crash log contains the following message:
*** Fatal Error ***
Address not mapped to object (signal 11)
Address: 0x468
Executing: gdb --quiet --batch --command=/tmp/gdb-respfile-LJxcaJ
Failed to create a crash report. Please make sure that 'gdb' is installed and present in PATH then crash again.
Current PATH: /usr/bin:/bin:/usr/sbin:/sbin
The crashes happen when I attempt to view certain cells as a 3D scene. For example, when attempting to view the exterior view of Balmora, or when attempting to view the St. Delyn Waistworks. Sometimes, the crash happens before the scene loads. Other times, the crash happens shortly after the scene loads, within a few seconds of me attempting to navigate within the 3D space.
I am able to successfully view and edit smaller cells (such as St Delyn North-Two, or other small interior cells), however, after a period of time of editing 3D scenes (positioning assets, deleting or adding assets), the CS editor will also crash, with no apparent pattern other than length of time.
