Oh, we've got another confirmed case of the scary runtime error. I guess now the question is, does anybody know of any memory corruption bugs in macOS and go1.15.5? I didn't see anything obvious.
runtime: gp: gp=0xc000802900, goid=0, gp->atomicstatus=0 runtime: g: g=0xc000602480, goid=0, g->atomicstatus=0 fatal error: bad g->status in ready https://gist.github.com/awoods187/e9289c706ddc529034368fd3a2a25323 On Wednesday, March 24, 2021 at 10:02:20 PM UTC-4 awer...@gmail.com wrote: > A situation has arisen a few times lately where we've seen segfaults that > have strange looking address values.
