go 1.19.1 - race detector tests - undefined reference to clock_gettime #55974
Description
What version of Go are you using (go version)?
1.19.1
Does this issue reproduce with the latest release?
Yes.
What operating system and processor architecture are you using (go env)?
CentOS 6
What did you do?
When building on CentOS 6/glibc-2.12 there seems to be a missing "-lrt" when linking these tests.
The same steps and tools work on CentOS 7.
