Thanks for the code example.
First, your sample needed a ";" between pic-> and s. without it, it
assumed it needed to lookup pic->s.
I've checked in updates to the analyzer debugger to capture and report
errors coming up out of the analyzer. This led me to discover that
the "VideoPicture" typedef was loosing the actual content.
I updated semantic-c.el to propertly capture the content of the
typedef, and now it correctly dereferences and completes for me.
The completion of s. has always worked for me.
If it continues to not work, you can use the
semantic-analyze-debug-assist again, and perhaps it will reveal some
better errors we can interpret.
Enjoy
Eric
