This looks like some kind of file corruption on the darwin machine.

ignore my earlier comments, they provide nothing new.

but, here are some interesting clues i've found may be helpful.

1. issue60434.go is 392B less that 512
2. the corruption offset of 'issue60434.go:8:10' by roughly caculation is 256.
