Description
There's a compiler panic that happens on one of the new functions. Looks like a compiler bug?
runtime/mgcmark_greenteagc.go:778:30: internal compiler error: '(*gcWork).tryStealSpan': panic during regalloc while compiling (*gcWork).tryStealSpan:
runtime error: invalid memory address or nil pointer dereference
