--- Comment #1 from law at redhat dot com ---
GCC now has the ability to replace a NULL pointer dereference with a trap
instruction. This is useful in a variety of contexts as a path with a NULL
pointer dereference is not standards conformant.
My recommendation would be to first test if -fno-isolate-erroneous-paths exists
as an option and use it for that test.

--- Comment #2 from Markus Trippelsdorf <markus at trippelsdorf dot de> ---
I think you should leave the *0 in gcc, because you'll break
all programs that have a custom handler otherwise.
For example Xorg also breaks without -fno-isolate-erroneous-paths
on my machine:
...
[ 59279.226] (EE) Illegal instruction at address 0x452dc0
[ 59279.232] (EE)
Fatal server error:
[ 59279.244] (EE) Caught signal 4 (Illegal instruction). Server aborting
