Re: [ES40-developers] Warning: device structures clobbered

[Brian W. <bdw...@in...>]

I've seen similar things (like segfaults and random crashes) after
rebuilding part of the binary if the .h files had changed and other
files that depended on them didn't get rebuilt.  

If you're on unix do a "make clean; make depend" and it shouldn't happen
after that...
