 Run-time error reaction

 When this happens, a fatal error has occured and the kernel
 can not continue. In linux, the equivalent would be a
 "kernel panic"

 This routine can be modified to suit your needs ...
 E.g. a red LED could light up. When using an
 emulator, you may set a breakpoint here.
 In the release builds of the library (R), this routine is not required
 (as no checks are performed).
 In the stack check builds (S/SP), only error 120 may occur.
 In the debug builds(D/DP), all of the listed errors may occur.

 The following are the current errorcodes (V3.20) :
 (Please refer to the documentation for more info)
