As an addition to the use of GDB you can also use the event recording in 
combination with -finstrument-functions:

https://docs.rtems.org/branches/master/user/tracing/eventrecording.html

You can use

|#define CONFIGURE_RECORD_FATAL_DUMP_BASE64_ZLIB|

|to dump the records in the fatal error handler. With the function 
instrumentation you get the sequence of function calls which resulted in 
the exception.
