This may be a bug in a particular plugin - illegal access in a debug
statement - or it may be a general problem with the way you've compiled
things.
I'd try turning on individual debug categories and see if it's a
particular thing that makes it crash, or (better) run it in a debugger
and catch the crash backtrace.
To turn on individual debug categories, use GST_DEBUG as a mask:
GST_DEBUG=*sink:5,identity:3 gst-launch videotestsrc ! identity !
fakesink
for example.
