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:
[New Thread 0x7fcd41ec1700 (LWP 8142)] [New Thread 0x7fcd41692700 (LWP 8143)] [New Thread 0x7fcd40e63700 (LWP 8144)] [New Thread 0x7fcd3bfff700 (LWP 8145)] [New Thread 0x7fcd3b7fe700 (LWP 8146)] [New Thread 0x7fcd3affd700 (LWP 8147)] [New Thread 0x7fcd3a7fc700 (LWP 8148)] [New Thread 0x7fcd39ffb700 (LWP 8149)] [New Thread 0x7fcd397fa700 (LWP 8150)] [New Thread 0x7fcd38ff9700 (LWP 8151)] [New Thread 0x7fcd2f9ea700 (LWP 8152)] [New Thread 0x7fcd2f1e9700 (LWP 8153)] ThreadSanitizer: longjmp() is not supported [Thread 0x7fcd2f1e9700 (LWP 8153) exited] [Thread 0x7fcd2f9ea700 (LWP 8152) exited] [Thread 0x7fcd38ff9700 (LWP 8151) exited] [Thread 0x7fcd397fa700 (LWP 8150) exited] [Thread 0x7fcd39ffb700 (LWP 8149) exited] [Thread 0x7fcd3a7fc700 (LWP 8148) exited] [Thread 0x7fcd3affd700 (LWP 8147) exited] [Thread 0x7fcd3b7fe700 (LWP 8146) exited] [Thread 0x7fcd3bfff700 (LWP 8145) exited] [Thread 0x7fcd40e63700 (LWP 8144) exited] [Thread 0x7fcd41ec1700 (LWP 8142) exited] [Thread 0x7fcd47858700 (LWP 8141) exited]
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!
