   Emacs is not supposed to crash, but if it does, it produces a
 @dfn{crash report} prior to exiting.  The crash report is printed to
 the standard error stream.  If Emacs was started from a graphical
-desktop, the standard error stream is commonly redirected to a file
-such as @file{~/.xsession-errors}, so you can look for the crash
-report there.

+directory of the Emacs process, in addition to the standard error

   The format of the crash report depends on the platform.  On some
 platforms, such as those using the GNU C Library, the crash report
 includes a @dfn{backtrace} describing the execution state prior to
 crashing, which can be used to help debug the crash.  Here is an

-  Optionally, Emacs can generate a @dfn{core dump} when it crashes.  A
-core dump is a file containing voluminous data about the state of the
