I apologize up front, I'm sure this isn't the right place to ask, but
I'm not sure where I should ask, instead. Hoping for some helpful hints
in that regard...
I'm using (trying to use...) the -fsanitize=thread feature. Though I'm
finding the diagnostics rather cryptic, that isn't my issue here.
Suddenly, a few days ago, I started getting this error while running the
app i'm testing:

The message about longjmp() is the issue. This app doesn't use longjmp
or siglongjump or any other of its cousins. It's possible that some 3rd-party
lib (Oracle??) might, but I don't know why it has been working for several
weeks and suddenly starts giving me this error...
Clues welcome, thanks!
