Not this way! This code is a tricky one. :) It is working by luck of the draw.
The cti_vm_throw should return to the code of ctiOpThrowNotCaught.

The "add r8, pc, #4 \n str r8, [sp, #-4]!" pair set the return address of
cti_vm_throw to the next instruction of "b cti_vm_throw".

It wasn't an accident to group those two function body in ARM trampolines. ;)

Fix these by adding the body of ctiOpThrowNotCaught after "b cti_vm_throw".
