There was a problem hiding this comment.
Efforts towards warning reduction are much appreciated.
- Removal of unreachable
BSON_THREAD_RETURNinBSON_THREAD_FUN (insert_docs, p)in test-mongoc-sample-commands.c (double-check: continues to behave as expected?).- Removal of UB null pointer arithmetic in
bson_md5_processin common-md5.c (double-check: continues to behave as expected?).- Removal of unused
errorparameter in_needs_on_demand_aws_kmsin mongoc-crypt.c (double-check: no error handling required?).
I double checked. These changes LGTM.

This PR addresses miscellanous GCC and Clang warnings. Verified by this patch.
Many of these warnings are not normally enabled and have relatively low significance, but imo are worth addressing regardless to improve the quality of the codebase.
Each commit in this PR documents the number of warnings addressed according to GCC 11.4 and Clang 15.0 Of course, the numbers are specific to my machine, environment, and project configuration, but they help describe the scope of impact.
Warnings in bundled library source code (specifically jsonsl) are left as-is.
In total, this PR addresses 21 GCC warnings and 1058 Clang warnings on my machine.
Most changes are fairly straightforward and rather mundane.
However, a few changes deserve greater scrutiny from the rest, just in case:
BSON_THREAD_RETURNinBSON_THREAD_FUN (insert_docs, p)in test-mongoc-sample-commands.c (double-check: continues to behave as expected?).bson_md5_processin common-md5.c (double-check: continues to behave as expected?).errorparameter in_needs_on_demand_aws_kmsin mongoc-crypt.c (double-check: no error handling required?).
