Actually it seems like it is more restricted towards a few instructions with memory operand. But if breakpoint is set to them at any point of execution they crash.
That means also breakpoint before and single stepping to problematic breakpoint will crash application. But single stepping over problematic instruction without breakpoint doesn't crash. That was adding to my earlier confusion why application crashes looked so random. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1850258 Title: First breakpoint at AVX instruction with memory operand causes SIGSEGV when tring to continue execution To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdb/+bug/1850258/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
