> This patch fixes the following SingleStep bugs:
> - Breakpoint was set for a wrong frame for regular bytecodes. The previous frame should
be used only for return type bytecodes
> - Bug with uninitialized disassembler field in breakpoints when no other breakpoint is
set in the place where SingleStep breakpoint is going to be created
> - Fixed exception RAISE state in breakpoints handler and exception event callback
> - Fixed race condition when instrumenting compiled method
> - Fixed function get_other_breakpoint_same_location
> - Fixed SingleStep location prediction
> The patch also adds a lot of tracing useful for debugging SingleStep code.
