Recover from segmentation fault

[hemant kumar]

Hi..
I am using DEFUNDLD..interface for defining my own functions..and adding them 
to octave.But sometimes few functions causes segmentation fault..inside 
octave.and thus octave terminates.
How can i make octave recover from segmentation fault.Like when my program 
tries to access invalid memory..then obviously a segmentation fault will 
occur..now i just want to make sure..that if it happens ,it will print an 
error..and not enitre octave will crash.

We tried using signal handler..and tried to catch sigsegv signal..but that 
results in a infinite loop.
