Last modified: 2016-08-11 03:49:58 EDT
Description of problem: Abrt caught find util crashing Version-Release number of selected component (if applicable): findutils-4.4.2-8.el6.x86_64 How reproducible: unknown Steps to Reproduce: 1. unknown, got caught as part of our test suite, repeating the command does not fail 2. 3. Actual results: abrt caught find crashing Expected results: no crashing Additional info: abrt report attached
Created attachment 1121387 [details] abrt report
Where is "our" test suite? How can one run it?
that is cluster test suite (so completely unrelated to find testing as such). find was just one of the commands we routinely use to locate our bits. To run it you must have working cluster environment. I can provide you with one if you find it a necessity to reproduce.
