You could try it this way if you really need a separate function.

The defer is not being run directly as a result of the panic.

func logPanic() {

This still not working.

Go has an unusual (clever!) property that anything whose address “escapes”
from your routine will magically be allocated on the heap _no matter if it
looks like heap or local allocation. Conversely, even explicit heap
allocations that don’t escape will/may be local (will up to 10 MiB).

Major update to library again:
- added full support of conditional formatting
- added support of comments
Also I created guide for most features:

When do you need to use mutexes? Which begs the question: When can multiple
coroutines trample on memory or a variable?
Doesn't each instance of a go routine get it's own stack (so, it's own
local copy of local vars). It would seem that the only
entities that it's possible to access from

1. Golang can be very verbose, for example checking if err != nil after a

Regarding building https://github.com/etcd-io/etcd.git with gollvm -- I

Others already replied about Oracle, and I don't want to go OT here, just a
small remark: you a wrong saying that VS Code is free. You are not paying

Yes, as the spec says, recover must be called directly by a deferred function.

Recently I found an issue in our product, panic can't be recoved in some
situation, I spend some time on it.

Go is Great (I've been waiting a long time for an opportunity to say that
:-) )
I use Go almost exclusively and do not cherish the thought of using
something else, although I could in a pinch.
I also stopped at Go1.10 for practical reasons. But at my age that is not
really that serious.
Guys, why not keep the discussion to the point. Oracle is quite irrelevant
here. The issue is the perception of Go among programmers.
