a) "I spent the week chasing down an apparent bug on one of the Standard Libraries we use."
or:
b) "I implemented connectivity with the Hong Kong stock exchange, improved our MT performance to get a 20% improvement on submitting trades, and identified a bug we were having with currency conversions as possibly being in one of the libraries we use, wrote a work-around for it, wrote the fix and tests up on our developer wikki, and submitted a report to the library vendor."
Now, I would say that(b) is of far more value for the company I work for and is at least as "professional" as (a).
Several times in my life I've been in situations where a) was more important because the bug was causing real issues now. In your industry a bug that miscalculates risk can cost billions of dollars. In my industry a bug can cause a safety system to fail and kill people.
It looks like we're in similar industries then based on your comment and if that's more or less the level you've been operating at on a weekly basis for decades then without a doubt you are a significantly more productive individual than I am and really kudos to you for it.
My point is mostly that not everyone is you though, similarly I don't presume everyone works like I do. Hence arguing that because you've done something for 30 years that it reasonably follows that everyone else should also do it is a really poor argument.

That's fine, but it does assume that a workaround exists and can be implemented within a reasonable amount of time. If you're talking about a bug in a library of convenient text processing utilities, that might well be the case. If you're talking about a bug in a security-related library that you rely on to authenticate instructions to make high-value trades, maybe not so much.
