Caliper Segmentation fault on Xeon Phi Knight landing #40

twang15 · 2017-07-03T19:10:16Z

I annotate LULESH with caliper macros. LULESH experienced segmentation fault with the following call stack information (More details, please refer to this caliper issue) :

Hey @twang15 , much appreciated. Any chance you could rerun it with GOTCHA_DEBUG set to 3? In the current state, I can't do much to test this (no KNL access). No stress if you can't, I have a request for KNL access in and will get you ready to go ASAP, but if you want quicker results it would be neat to be able to see the debug info.

Best,

David

Hey David, I have set that environment variable. But I did not see any debug information. Please let me know where I should look for it? Is it dumped to a file or on the screen? I am actually at B315 now. If you want to debug it here, I can grant you access to KNL.

Sure, have an office number? I'll be right over

Hey @twang15 : please excuse the slow fix. We're caught up on #26, I have a candidate fix to try for your bug, but that needs to be merged first. I believe @daboehme may be hiding some of the GOTCHA'isms from you so your Caliper stuff works, but if it doesn't I'd expect a fix in a few weeks.

hariharan-devarajan · 2023-10-05T06:21:56Z

@daboehme Is this still a issue?

daboehme · 2023-10-05T16:07:14Z

@daboehme Is this still a issue?

No idea, might have been fixed with the recent updates. Since it's 6 years old I believe we can mark it as closed.
