+// of your program, and keep it around for the entire time you want to
+// have crash handling active (typically, until shutdown).
+// (NOTE): There should be only be one this kind of exception handler
+// object per process.
+//
+// If you want to write minidumps without installing the exception handler,
+// you can create an ExceptionHandler with install_handler set to false,
+// then call WriteMinidump.  You can also use this technique if you want to
+// use different minidump callbacks for different call sites.
+//
+// In either case, a callback function is called when a minidump is written,
+// which receives the full path or file descriptor of the minidump.  The
+// caller can collect and write additional application state to that minidump,
+// and launch an external crash-reporting application.

+// in Linux kernel at the time of writing. Thus, breakpad can no longer

+// inserted in between some .text sections, it tries to infer the names and
+// offsets of the segments, by looking at segments immediately precede and
+// succeed them.
+//
+// For example, a text segment before hugepage optimization

+// Minidumps are a Microsoft format which Breakpad uses for recording crash
+// dumps. This code has to run in a compromised environment (the address space
+// may have received SIGSEGV), thus the following rules apply:
+//   * You may not enter the dynamic linker. This means that we cannot call
+//     any symbols in a shared library (inc libc). Because of this we replace
+//     libc functions in linux_libc_support.h.
+//   * You may not call syscalls via the libc wrappers. This rule is a subset
+//     of the first rule but it bears repeating. We have direct wrappers
+//     around the system calls in linux_syscall_support.h.
+//   * You may not malloc. There's an alternative allocator in memory.h and
+//     a canonical instance in the LinuxDumper object. We use the placement
+//     new form to allocate objects and we don't delete them.

+// ProtectedMemoryAllocator
+//
+// A very simple allocator class which allows allocation, but not deallocation.
+// The allocations can be made read-only with the Protect() method.
+// This class is NOT useful as a general-purpose memory allocation system,
+// since it does not allow deallocation.  It is useful to use for a group
+// of allocations which are created in the same time-frame and destroyed
+// in the same time-frame.  It is useful for making allocations of memory
+// which will not need to change often once initialized.  This memory can then
+// be protected from memory smashers by calling the Protect() method.

+// ExceptionHandler can write a minidump file when an exception occurs,
+// or when WriteMinidump() is called explicitly by your program.
+//
+// To have the exception handler write minidumps when an uncaught exception
+// (crash) occurs, you should create an instance early in the execution
+// of your program, and keep it around for the entire time you want to
+// have crash handling active (typically, until shutdown).
+//
+// If you want to write minidumps without installing the exception handler,
+// you can create an ExceptionHandler with install_handler set to false,
+// then call WriteMinidump.  You can also use this technique if you want to
+// use different minidump callbacks for different call sites.
+//
+// In either case, a callback function is called when a minidump is written,
+// which receives the unqiue id of the minidump.  The caller can use this
+// id to collect and write additional application state, and to launch an
+// external crash-reporting application.
+//
+// It is important that creation and destruction of ExceptionHandler objects
+// be nested cleanly, when using install_handler = true.
+// Avoid the following pattern:
+//   ExceptionHandler *e = new ExceptionHandler(...);
+//   ExceptionHandler *f = new ExceptionHandler(...);
+//   delete e;
+// This will put the exception filter stack into an inconsistent state.
