I just upgraded from llvm 2.8.1 to llvm 2.9
I do not have crash anymore, BUT once the multiresolution modifier has 7+
subdivision, Blender is extremely slow.
Well not all Blender, at least the selection process is.
It goes like this :
- when doing nothing blender use <5% cpu
- right click in the scene => cpu goes to 100% for 10 seconds
- then cpu usage goes back to normal
Using gdb, I paused randomly Blender execution when cpu was high, and it always
gave me this stacktrace :
