@codesboy can you confirm that you are using the released 1.15 sources and not the beta/alpha.

cc @cherrymui
As this was supposed to be fixed in #39905

@AlexRouSg YES . I use go 1.15 sources: https://golang.org/dl/go1.15.src.tar.gz
It fixed in a4ba411
but this problem has bobbed up again.I need help.

If you need it to compile urgently, you can try editing src/cmd/link/internal/ld/fallocate_test.go and adding a t.Skip("fallocate is not supported") at the start of the function.

Thank you for this report @codesboy and welcome to the Go project! Thank you for the response @AlexRouSg and suggestion for a fix.

@codesboy your report says that you are using Go1.12.9 yet you just replied to @AlexRouSg in #41127 (comment) that you are using Go1.15. Could you please re-verify the bug report? Could you perhaps run git log | head -n 10 in your Go tree and report that? Thank you.

Hi Emmanuel, I think he's building the 1.15 source tree with 1.12.9.

Thanks @networkimprov for the clarification, my apologies, I missed that in the report (and was reading on my iPad) @codesboy stated the problem.

@networkimprov @odeke-em Yes! i'm installing Go1.15 from source(https://golang.org/dl/go1.15.src.tar.gz) with go compiler version 1.12.9.
Thanks in advance for your help.

Thanks for the report. What version of macOS are you running? What file system are you running on (if it is not the default)? It is interesting that it got 8 fewer blocks. Is the failure reproducible? Thanks.
