Are you asking what I would do in case sigabrt is received by my 
program instead of sigsegv ?

I would install the same cleanup functionality in this handler. 
Zero out memory, send a signal to stop an engine or whatever 
mandatory clean up is required and return from the handler. Then 
let the OS take care of the rest, i.e. terminate the process.
