Incorrect behaviour

Open MAME with debugger active (-debug -window megaduck), place cursor above the debugger above and (very) quickly scroll down (swiping with 2 fingers on the touchpad) towards/past the end of the debugger log, then the application will crash with message: "libc++abi: terminating due to uncaught exception of type std::length_error: vector" If I scroll down slowly or normally then no crash occurs only when attempting to scroll quickly.

It does not happen when scrolling up (towards/past the start of the debugger log), nor does it happen in our debugger views as far ass I could see.

The crash happens with multiple drivers, so I assume it is a generic issue.

I do not know if a similar crash can happen on other OSes.
