rr replay error on ARM64 (AWS c6g.4xlarge)

Open zhongweiy opened this issue 2 years ago • 3 comments

Hi, there,

When I set a breakpoint and run "continue", rr will run to the following error. But if I do not set the breakpoint and run "continue", it is OK. How can I fix it?

My environment is c6g.4xlarge AWS Graviton instance. Kernel is 6.2.0-1011-aws #11~22.04.1-Ubuntu. GDB 13.2. rr version 5.6.0.

Are you using a software or hardware breakpoint?

Hi, there,

When I set a breakpoint and run "continue", rr will run to the following error. But if I do not set the breakpoint and run "continue", it is OK. How can I fix it?

Hi, there,

When I set a breakpoint and run "continue", rr will run to the following error. But if I do not set the breakpoint and run "continue", it is OK. How can I fix it?
