Initialization fails when running go test -race on a module which includes gozstd.

[Villenny]

Running any test or benchmark from this file with -race will cause the below error

The error failed to allocate 0x000000a61000 (10883072) bytes at 0x200dc6f9fc000 (error code: 87) suggests that the host system doesn't have enough RAM for completing the test with race detector enabled. Try running the test on a machine with more RAM.
