I think no one here is interested in that except you.
RTL Trap means Run Time Library Trap. Run Time Library is a set of functions that deal with semaphores, dynamic memory, etc. I don't know the whole list of things.
There is a special function that's called by runtime library when the rest of firmware does something wrong like releasing semaphore which hasn't been reserved. This function writes "RTL Trap Error" crash log somewhere and shuts the unit down.
