On the use of C++ exception handling

Dear all, I've been investigating the use of C++ exception handling constructs in open-source C++ projects (including musescore). Currently, I am conducting a survey on this subject and I would really appreciate if you could contribute to this research by answering a few questions.

The survey is available on-line:

All the best,

Rodrigo.
