Since CL 282892, functions are always compiled before closures. To do that, when walking the closure, it is added to its outer function queue for scheduling compilation later. Thus, a closure may be added to queue more than once, causing the ICE dues to being compiled twice. To fix this, catching the re-walking of the closure expression and do not add it to the compilation queue. Fixes #49029 Change-Id: I7d188e8f5b4d5c4248a0d8e6389da26f1084e464 Reviewed-on: https://go-review.googlesource.com/c/go/+/357960 Trust: Cuong Manh Le <cuong.manhle.vn@gmail.com> Run-TryBot: Cuong Manh Le <cuong.manhle.vn@gmail.com> TryBot-Result: Go Bot <gobot@golang.org> Reviewed-by: Keith Randall <khr@golang.org>
