Unfortunately I cannot reproduce the issue (on linux).

maybe you could run blender from the commandline with the --debug option and attach the output as a txt file here?

Marking as incomplete until we have an answer...

Does this still happen with current branches (blender2.8 and master) builds?

got the same crash with different versions.

Doing some debug the problem is in undo_system.c line 457

if (us->name[0] == '\0') {

	BLI_strncpy(us->name, name, sizeof(us->name));
  }

The value of "name" var is NULL, so the BLI_* func fails due NULL Pointer.
