select * from TIFLASH_REPLICA, error
1105 - runtime error: invalid memory address or nil pointer dereference
Checked system memory, memory is sufficient
A typical error caused by assigning a value to a Go pointer without initializing the pointer first.
It is recommended to post the table structure (after desensitization) to check the field types.
I don’t understand, this is a system table, you can view the table structure.
You are the first to try it, I suggest the official team give you a testing fee.
It may be necessary to provide the reproduction steps of this suspected bug to better determine whether it is indeed a bug.
How many tables currently have TiFlash replicas configured?
Can we investigate which specific table is causing the issue?
I did some random testing on my side and couldn’t reproduce the problem…
I didn’t expect such a commonly used SQL to have bugs in the new version.
This indicates that we should conduct thorough testing before using new data versions.
My tests show no issues. Have you checked the character set of the Linux system?
Please provide the TiDB error log at the time of this error message, specifically the panic error stack, to facilitate problem analysis.
I encountered this issue before, it was because the default value in the data did not meet the requirements. You can check it out.
