SIGILL under gdb for AIX 64 bit binaries

Hello,
       When i run a program on command line it runs fine. But when i
run it gdb it gives me a SIGILL.
       I know that is a problem with the code because dbx for AIX also
gives the SIGILL instruction.
       But i've been not able to convince people in my organization it
is a problem with code.

       What they do is they 'c' (continue) in gdb when it hits a
SIGILL and keep on continuing 2 times until it crashes somewhere else
in the code.

       I wanted to know these 2 questions :

       1) Once it hits a SIGILL can we continue and go to the next
crash and so on ? Is this valid .

        2) How does gdb allow to continue on a SIGILL ?
