I see the same bug with different stack traces in different applications, but always in qt6-qtbase's AESHashSeed::state1() I suspect that this issue happens because a CPU instruction is used that is not supported by my CPU or that the compiler generated incorrect code. My CPU is a Intel Core i5-650, this model: https://ark.intel.com/content/www/us/en/ark/products/43546/intel-core-i5-650-processor-4m-cache-3-20-ghz.html I cannot reproduce these crashes on a different machine with a more recent CPU (Intel Core i5-2450M, this model: https://ark.intel.com/content/www/us/en/ark/products/53452/intel-core-i5-2450m-processor-3m-cache-up-to-3-10-ghz.html ) @Gilbert: Is it possible that you are also running Fedora on a very old CPU? Maybe also one of the first 2 Intel Core families? Or an AMD CPU from the same time (around 2010)?
