    Description

      I doubt this will be easily reproducible (I was just editing a float literal in C++), but I'm creating it in case someone hits the same issue and searches for the same function in the stack trace.

      Exception Type:        EXC_BAD_ACCESS (SIGSEGV)

Exception Note:        EXC_CORPSE_NOTIFY
