 // This code is a little fragmented. Different functions of the ExceptionHandler
 // class run in a number of different contexts. Some of them run in a normal
 // context and are easy to code, others run in a compromised context and the
 // restrictions at the top of minidump_writer.cc apply: no libc and use the
 // alternative malloc. Each function should have comment above it detailing the
 // context which it runs in.
