[Crash-utility] Question about extension modules

[Fei, Jie/费 杰]

Hello Dave,

Several weeks ago there was a bugzilla report about crash-trace-command
which was caused by load_module structure change:
https://bugzilla.redhat.com/show_bug.cgi?id=1520825

We can solve the problem by updating crash-trace-cmd with the latest
crash-devel package.

And I'm wondering if there is a need for trace.c to have an error check
function for this kind of data structure change problems or for crash to 
have
some "extensions" test processes when new version is released which can 
find
these problems ealier.

Thanks,
Fei
