No, you should only look at the first compile error in that file:
src/libavformat/chromaprint.c:42:24: error: field 'ctx' has incomplete type
ChromaprintContext ctx;
^~~
This is the actual error.
Whatever the compiler comes up with for cpr->ctx in the place you quoted
might be garbage, but at that point it is already game over.
